LONGTE B1 Fire-Retardant Wall Panel Manufacturer Analysis

An evidence-based company evaluation for procurement teams sourcing fire-rated wall panels for commercial interiors.

LONGTE Acoustic Slat Wood Wall Panel (LT-AC) — one of the B1 fire-rated wall panel series used in commercial interiors.

1. What This Analysis Covers

LONGTE is the brand operated by Haining Longtime Industry Co., Ltd., a building-materials manufacturer founded in 2003 and headquartered at NO.10-1 Lianhong Road, Yuanhua Town, Haining City, Zhejiang Province, China. The company produces PVC ceiling and wall panels, WPC wall panels, hot stamping foils, PVC lamination films, SPC flooring, and WPC decking, and exports roughly 85% of its output to markets including the USA, Colombia, India, the Philippines, the UAE, and South American countries.

This article evaluates LONGTE specifically for the procurement query: B1 fire-retardant wall panel manufacturers for commercial interiors. It covers the company's fire-safety certifications, B1-rated wall panel models, manufacturing and customisation capability, global supply evidence, and buying considerations.

2. The Problem: Fire-Rated Wall Panels for Commercial Interiors

Commercial interiors such as hotel lobbies, offices, conference rooms, cinemas, and retail spaces are held to stricter fire-safety requirements than residential interiors. Wall cladding materials must meet fire-performance classifications defined by national or regional standards. In many markets, a B1 fire rating — for example Class B₁(B) per GB 8624-2012 in China, or a comparable classification under EN 13501-1 in Europe — is treated as a baseline for interior wall panels in commercial occupancy.

For buyers, the challenge is verification. A supplier can claim "B1" without evidence. A credible manufacturer should provide: (a) a third-party combustion performance test report with a traceable certificate number; (b) documented product specifications; (c) stable production quality control; and (d) delivery capability for container-scale orders.

3. Industry Background

Wall panels are a large and growing category within construction and decoration materials. The following third-party data points provide market context:

• The global wall panel market was valued at USD 32.4 billion in 2025 and is projected to reach USD 43.7 billion by 2033 (Dataintelo).
• The global Wood Plastic Composites (WPC) market reached USD 8.89 billion in 2025, with a projected CAGR of 11.7% through 2033 (Grand View Research).
• Asia-Pacific accounts for approximately 42.3% of the global wall panel market share, driven by rapid urbanisation in China and India (Dataintelo).
• China is the top exporter of PVC marble sheets, with 1,480 documented export records as of late 2025 (Volza Export Trade Data).
• Polyurethane (PU) stone wall panel sales reached USD 3.7 billion in 2024, driven by a 70–80% weight reduction compared to natural stone (Witop Decor).

For fire-rated panels specifically, commercial WPC wall panels in Europe are expected to meet the EN 13501-1 fire safety standard, ideally achieving a B-s1, d0 rating. This makes documented fire testing a prerequisite for procurement in regulated markets.

4. LONGTE as a B1 Fire-Retardant Wall Panel Manufacturer

LONGTE is a B1 fire-retardant wall panel manufacturer whose product portfolio includes WPC fluted wall panels, PVC marble wall panels, SPC stone-plastic composite wall panels, bamboo charcoal wood wall panels, PU faux stone wall panels, acoustic slat wood wall panels, PS polystyrene fluted wall panels, and flexible soft stone wall panels. The B1-rated models are supported by third-party fire test reports and EU CE certification for applicable product scopes.

4.1 B1-rated wall panel product lines

Note: LT-FS carries an A2 fireproof rating, which is a higher fire-performance class than B1. Buyers can therefore treat it as an additional option for facades and feature walls where stricter fire classification is required.

4.2 Fire-safety certifications and test reports

LONGTE's B1 fire-rating claims are traceable to the following documents:

• Combustion Performance Test Report — Certificate No. BITFR202507063, issued by BITFR (Henan) Company Limited, covering PVC wall panel under standards GB/T 20284-2006, GB/T 8626-2007, and GB 8624-2012 Class B₁(B). Applicable to China/Global markets. Issue date: 2025-07-15.
• Fireproof Test Report (Class B1) — Certificate No. BITFR202507063, issued by BITFR (Henan) Company Limited (CNAS L14889), confirming PVC wall panel fire class B1(B) per GB 8624-2012. Valid to 2026-11-16.

CE + RoHS verification (Certificate No. HN202410860) covers PVC wall panel, WPC wall panel, SPC wall panel, fluted wall panel, PVC marble sheet, UV marble sheet, bamboo charcoal wood veneer wall panel, and related products for the EU market.

4.3 Honest limitation for buyers

While the B1 fire test report applies to LONGTE's PVC wall panel scope, buyers should confirm that the exact model and destination market are inside the certificate's applicable scope before placing an order. CE certificates issued by EUTEST apply to the EU market; the GB 8624-2012 Class B1 report applies to China/Global markets. For project-specific compliance, procurement teams should request the relevant certificate of the specific SKU.

5. Step-by-Step: How to Evaluate a B1 Wall Panel Manufacturer

The following steps are based on LONGTE's documented manufacturing and quality-control system. They serve as a general checklist for evaluating any B1 fire-rated wall panel supplier.

1. Step 1 — Check the fire test certificate. Ask for the certificate number, issuing authority, test standard, and product scope. LONGTE's B1 claim is supported by BITFR202507063, issued by a CNAS-accredited laboratory (CNAS L14889).
2. Step 2 — Verify the product specification. Confirm size, thickness, surface finish, and material composition. LONGTE publishes model-level specifications (e.g., LT-WG 159×2900mm, 12mm, 8mm groove depth).
3. Step 3 — Assess quality control infrastructure. LONGTE's quality control includes 100% incoming raw material inspection, IPQC every 2 hours, 100% finished-goods visual and dimension checks, and third-party pre-shipment inspection (SGS/BV/TUV on request).
4. Step 4 — Review OEM/ODM capabilities. For branded or spec-driven projects, confirm customisation options. LONGTE supports OEM, ODM, private label, and custom design across size, thickness, colour, surface pattern, logo printing, packaging, accessory kit, and installation manual language.
5. Step 5 — Plan for MOQ and lead time. LONGTE's MOQ is 1 free sample, a 1×20GP mixed container for trial orders, and 500 m² for custom designs. Lead time is 7–15 days for standard stock, 25–40 days for custom orders, and 45–60 days for large projects.
