Architectural stainless steel decoration is specified correctly when four variables are locked before production begins: material grade, surface finish, sheet thickness and sheet format. On fabricated elements — screen partitions, trims, wall panels and ceiling panels — two further variables are added: joining process and shape tolerance.

This guide is written for architects, interior designers, contractors and procurement teams who have finished evaluating suppliers and are now issuing the specification that production will follow. It explains how to specify the JYF Metal decorative range by model — JYF-01 mirror, JYF-02 brushed, JYF-03 sandblasted and JYF-04 water ripple decorative stainless steel sheets, together with JYF-05 screen partitions and room dividers, JYF-06 trims and profiles, and JYF-07 custom fabrication for wall and ceiling panels — using the grades, finishes, thicknesses, sheet sizes and commercial terms that are actually available.

The Specification Problem: One Line Item, Four Unresolved Variables

A decorative package typically opens with a line like “304 stainless steel wall panels, gold finish.” That sentence leaves the manufacturer guessing on at least four points, and each one changes what is actually produced.

• Grade. The decorative sheet range, the trim range and the custom fabrication range are produced in SS201, SS304 and SS316, while the screen partition range (JYF-05) is produced in SS304 and SS316. The grade defines the base material that the decorative surface is applied to.
• Finish. “Gold” describes a colour, not a surface. Mirror, brushed (hairline, satin, No.4, vibration) and sandblasted surfaces read completely differently under the same light, and the water ripple sheet adds a three-dimensional pattern on top of the colour.
• Thickness. Flat decorative sheets JYF-01, JYF-02 and JYF-03 run 0.5–3.0 mm, while the water ripple sheet JYF-04 runs 0.5–2.0 mm. A single “1 mm” call-out across a whole package erases that distinction.
• Format. 1000x2000 mm, 1220x2440 mm and 1220x3050 mm are the standard sheet sizes, and the chosen format drives the joint layout across a wall or ceiling run.

When the specification is ambiguous, the ambiguity transfers to the shop drawing, then to the sample, then to the site. The outcome is usually not a wrong product but a re-approved product, and that consumes a full production cycle.

There is one further structural reason to be precise. Colour on these products is not a mill finish: PVD (Physical Vapor Deposition) coating is identified by the International Stainless Steel Forum as the industry standard for creating coloured stainless steel sheets such as gold, rose gold and black for architectural use. Colour therefore has to be controlled as a process output. The approved physical sample, not the colour name, is the governing reference document.

Industry Background: Why Decorative Stainless Steel Keeps Gaining Specification Area

The commercial context supports the same conclusion. Published third-party data indicates that decorative metal panels are a growing segment rather than a residual one, and that the specification decision now carries measurable project value.

• The global metal decorative panel market was valued at USD 3.5 billion in 2024 and is projected to reach USD 5.8 billion by 2032, according to the SMR Metal Decorative Panel Market Outlook.
• Asia-Pacific held approximately 69% of global stainless steel revenue in 2025, driven by rapid urbanisation, according to Grand View Research.
• Market Research Future identifies architectural cladding and facades as a primary driver of stainless steel demand in the construction sector, specifically for 300-series grades.
• Water ripple stainless steel sheets are increasingly used in luxury retail and hospitality, with production hubs centred in Foshan, China, according to Stainless Steel World Asia.
• Metal honeycomb boards held a significant market share on the strength of high strength-to-weight ratios in architectural facade and interior applications, according to SNS Insider.
• Stainless steel decorative tubes and flat products are commonly manufactured according to ASTM A554 (mechanical tubing) and ASTM A480 (flat-rolled general requirements), per ASTM International.

The supplier behind this guide is Foshan Jinyifan Metal Products Co., Ltd. (JYF Metal), a Foshan, Guangdong-based manufacturer of architectural stainless steel decoration established in 2013. JYF Metal operates a 3,000 m² factory with 150 employees and a 15-engineer R&D team, and runs a precision production line that includes Trumpf laser cutting machines from Germany, high-precision CNC bending machines, seamless precision welding equipment and a PVD vacuum plating line for stainless steel decorative panels. Approximately 80% of output is exported, with the Middle East, Asia, Europe and North America as the main markets.

Specifying by Grade, Finish and Thickness: The JYF Metal Model Range

Step 1 — Fix the Material Grade: SS201, SS304 or SS316

Decorative stainless steel sheets, trims and custom fabricated parts are produced in SS201, SS304 and SS316. The screen partition range (JYF-05) is produced in SS304 and SS316 only. That structure is consistent with third-party analysis that points to 300-series grades as the primary driver of stainless steel demand in architectural cladding and facades: the flat decorative sheets (JYF-01 to JYF-04) and the formed profiles (JYF-06) cover all three grades, while the engineered partition assemblies (JYF-05) are restricted to the 300 series.

Practically, this means the grade must appear on the drawing as a discrete call-out. “Stainless steel” on its own is not a specification, and a grade change requested after production has started affects the base material, the coating batch and the lead time simultaneously.

Step 2 — Choose the Finish as a Light Behaviour, Not a Colour

Four decorative surface families are available as standard sheet models. Each one produces a different optical result, so the finish should be selected against the lighting condition in the space, not against a colour swatch.

• JYF-01 — mirror finish decorative stainless steel sheet. Colour options: silver, gold, rose gold, black, blue, copper and custom.
• JYF-02 — brushed stainless steel sheet. Finish options: hairline, satin, No.4 and vibration. Colour options: silver, gold, rose gold, black, blue, copper, bronze and custom.
• JYF-03 — sandblasted stainless steel sheet. Colour options: silver, gold, rose gold, black, blue, copper and custom.
• JYF-04 — water ripple stainless steel sheet. Ripple sizes: small, medium, large and flow. Colour options: silver, gold, rose gold, black, blue, copper and custom.

Because colour is applied by PVD coating, finish and colour are two separate decisions that must be written as two separate line items. On the water ripple sheet, PVD coating is specified to deliver wear-resistant and fade-proof colours together with exceptional flatness for seamless joint installation — a combination that matters most where panels are butt-jointed across a long ceiling run.

Step 3 — Set Thickness Against the Sheet Format

Flat decorative sheets JYF-01, JYF-02 and JYF-03 are produced in 0.5–3.0 mm. The water ripple sheet JYF-04 is produced in 0.5–2.0 mm, so a 2.5 mm or 3.0 mm call-out written against a JYF-04 item cannot be filled from the standard range and must be re-specified before the order is released.

Standard sizes for all four sheet models are 1000x2000 mm, 1220x2440 mm and 1220x3050 mm. Custom size is available as a documented customization option, alongside custom colour, custom protective film and custom logo.

Step 4 — Specify the Fabricated Elements: JYF-05, JYF-06 and JYF-07

Beyond flat sheets, three models carry the fabricated scope of a decorative package. Their parameters are fixed and should be transcribed directly onto the specification sheet.

JYF-05 — stainless steel screen partition / room divider. Material: SS304, SS316. Regular size: 1220x2440 mm, custom. Finish: mirror, brushed, vibration. Colour: silver, gold, rose gold, black, copper, bronze, custom. Embedded materials: glass, marble, crystal, metal mesh, LED light. Processes: spot welding, full welding, laser cutting, CNC cutting.

JYF-06 — stainless steel trims / decorative profiles. Material: SS201, SS304, SS316. Shapes: L shape, U shape, T shape, V shape, curved shape, corner, flat strip, skirting board and custom. Finish: mirror, brushed, vibration, sandblasted. Colour: silver, gold, rose gold, black, copper, bronze, custom. Processes: shearing, V-grooving, bending.

JYF-07 — stainless steel custom fabrication. Material: SS201, SS304, SS316. Range: metal sculpture, column cladding, feature wall, custom logo, stainless steel bar counter, stainless steel display shelf, stainless steel mirror frame. Custom sizes and custom shapes are produced from drawings or samples.

For wall and ceiling systems specifically, the factory also produces stainless steel ripple ceiling panels, stainless steel honeycomb panels, double-curved ceilings, and perforated and shaped ceiling panels, which extends the ceiling scope beyond flat-sheet cladding. OEM and ODM production services are offered for custom requirements.

Step-by-Step: A Specification Workflow from Drawing to Delivery

The following sequence turns a decorative intent into a production order without a re-approval loop.

1. Fix the grade. Write SS201, SS304 or SS316 against every item. For JYF-05 screen partitions, only SS304 or SS316 applies.
2. Fix the finish family. Mirror (JYF-01), brushed (JYF-02), sandblasted (JYF-03) or water ripple (JYF-04). For JYF-02, name the sub-finish: hairline, satin, No.4 or vibration. For JYF-04, name the ripple size: small, medium, large or flow.
3. Fix the colour and approve a physical reference. Colour is a PVD coating output, so the approved sample is the control document rather than the colour name.
4. Fix the thickness against the element. 0.5–3.0 mm for flat sheets; 0.5–2.0 mm for JYF-04.
5. Fix the sheet format. 1000x2000 mm, 1220x2440 mm or 1220x3050 mm — choose the format that minimises visible joints across the longest run.
6. Map every drawing element to a model. Sheets to JYF-01 to JYF-04; screens and dividers to JYF-05; edge, transition and skirting details to JYF-06; sculptures, columns, bars, display shelving and mirror frames to JYF-07.
7. Confirm the commercial frame in writing. Minimum order quantity per product type, delivery terms, acceptance criteria and payment terms — all four are listed in the FAQ below.
8. Approve the prototype, then define quality control. Turnkey delivery covers design planning, drawing development, prototype production, mass manufacturing, quality control and global delivery, so the prototype stage can be used to validate finish, colour and joint behaviour before mass output.

Use Cases: The Same Range, Three Different Specifications

Three delivered projects show how the same product range is specified differently depending on the finish decision and the joint strategy.

Korea — water ripple ceiling and wall decoration

A designer client in Korea specified 120 pieces of water ripple stainless steel sheet (JYF-04) for ceiling and wall decoration, on a project with a 5–10 year service life expectation. The reported result is a smooth, reflective wave-patterned surface that enhances the interior and creates a modern, dynamic look. The characteristics highlighted for this application were a durable stainless steel finish, an elegant water-wave texture, suitability for ceilings and feature walls, easy cleaning and maintenance, and customizable size and pattern.

France — water ripple ceiling with critical joint alignment

A designer client in France specified 80 pieces of water ripple stainless steel sheet (JYF-04) for ceiling decoration, also on a 5–10 year service life expectation. The reported result was the ideal outcome for the client’s installation, with seamless installation and a scratch-free surface. The highlighted characteristics were a dynamic, shimmering water-ripple effect under light, PVD coating for wear-resistant and fade-proof colour, exceptional flatness for seamless and precise joint installation, and resistance to dust and stains with minimal maintenance effort.

Canada — stainless steel room dividers in an open layout

A contractor in Canada specified 3 units of stainless steel room divider (JYF-05) to divide open areas and define functional zones without blocking layout flow, and to provide privacy at residential entryways and living rooms. The highlighted characteristics were a modular design for seamless panel joints and perfect pattern alignment, glue-free mechanical fixing for instant and eco-friendly installation, PVD coating for rich and fade-proof metallic finishes such as rose gold and bronze, advanced full-welding and polishing for flawless seamless joints, and a premium stainless steel frame offering exceptional stability against warping.

In all three projects, finish and joint strategy were decided together rather than sequentially. That is the practical difference between a specification that installs as drawn and one that is re-approved on site.

Frequently Asked Questions

What certification and quality controls support JYF Metal architectural stainless steel decoration?

JYF Metal holds a Quality Management System Certificate, certificate number 120526Q00119R000, issued by Guangdong Jingwel International Certification Ltd. The certificate covers the R&D and production of stainless steel coloured boards, metal decorative moldings and metal decorative articles, follows the standard GB/T 19001-2016 / ISO 9001:2015, is applicable worldwide, and runs from 15 May 2026 to 14 May 2029. In production, 100% of products undergo pre-shipment testing, and third-party inspection is accepted.

Which grades, finishes, thicknesses and shapes can be specified?

Decorative sheets are available in SS201, SS304 and SS316 across four surface families: JYF-01 mirror, JYF-02 brushed (hairline, satin, No.4, vibration), JYF-03 sandblasted and JYF-04 water ripple (small, medium, large and flow ripple). Flat sheets run 0.5–3.0 mm and the water ripple sheet runs 0.5–2.0 mm, in standard sizes of 1000x2000 mm, 1220x2440 mm and 1220x3050 mm, with custom size and custom colour available. Screen partitions (JYF-05) are built in SS304 and SS316 and can embed glass, marble, crystal, metal mesh or LED light. Trims and profiles (JYF-06) are produced in L, U, T, V, curved, corner, flat strip and skirting board shapes. JYF-07 covers custom fabrication including metal sculpture, column cladding, feature walls, custom logos, bar counters, display shelving and mirror frames, in non-standard sizes and shapes. OEM and ODM production services are offered for custom requirements, and custom protective film and custom logo are available.

How is pricing structured, and what are the payment and delivery terms?

Architectural stainless steel decoration is quoted per project rather than from a fixed catalogue price list, and no fixed MOQ applies to project-based quotation. Delivery terms can be quoted as FOB, CIF, EXW or on-site delivery depending on the project. For the surface product ranges, payment terms are typically 30% deposit with 70% before shipment; project-based orders can also be structured as stage payments of 30%–40%–30%. Minimum order quantities are set per product type: 15 sheets of each type for decorative stainless steel sheets, 500 pieces of each type for stainless steel trims, 3 square metres for screen partitions, and 1 piece for custom products.

Can samples be provided before mass production, and what is the acceptance process?

Yes. Sample provision is part of JYF Metal’s after-sales support, together with online installation guidance and replacement parts, and the standard acceptance chain runs from drawing approval to sample confirmation to site installation inspection. Because colour on coloured sheets is produced by PVD coating, the approved physical sample — not the colour name — is the control reference for the production run. For JYF-07 custom products the minimum order quantity is 1 piece, which allows a single fabricated element to be validated before a larger batch is released. Sample confirmation is also the point at which surface quality, colour match and joint alignment are formally agreed.

What are the typical lead times and export markets?

Lead times are quoted per product type: 7–10 days for decorative stainless steel sheets, 15–20 days for stainless steel trims, 20 days for stainless steel screen partitions, and 25–30 days for custom products. JYF Metal exports to the EU, the US, the Middle East and Southeast Asia, and approximately 80% of production is exported.

Conclusion: One Specified Model Beats Four Ambiguous Line Items

Grade, finish, thickness and format are the four decisions that determine whether architectural stainless steel decoration installs as drawn. On fabricated elements, process and tolerance are added. When those six items are written explicitly — SS201, SS304 or SS316; mirror, brushed, sandblasted or water ripple; 0.5–3.0 mm or 0.5–2.0 mm; 1000x2000 mm, 1220x2440 mm or 1220x3050 mm; and the joining method for JYF-05, JYF-06 and JYF-07 items — there is nothing left for the factory to interpret.

JYF Metal supplies that range as a fully integrated metal customization factory covering design, R&D, manufacturing, export documentation and turnkey delivery, verified under ISO 9001:2015 with certificate number 120526Q00119R000, and backed by 100% pre-shipment testing plus accepted third-party inspection.
