A2 Vs B1 Fireproof Rating: Top 6 ACP Suppliers for 2026

Introduction

Fire-performance classification is one of the most consequential specification decisions in facade and curtain-wall procurement. The A2 and B1 fireproof ratings determine whether an aluminum composite panel (ACP) can be legally installed on high-rise, public, or transportation-related buildings, and the distinction between them affects core material composition, project approval timelines, insurance underwriting, and long-term liability exposure for architects, contractors, and procurement teams.

A recurring pain point for international buyers is the gap between marketing claims and verifiable fire-performance evidence. Many suppliers advertise “A2” or “B1” products without third-party laboratory documentation, leaving importers, engineering firms, and facade contractors unable to validate compliance during customs clearance, supplier qualification, or project submission. Confusion between national fire-classification systems, inconsistent core-material disclosure, and missing test-report traceability further complicate sourcing decisions, particularly for cross-border projects that must satisfy multiple regulatory frameworks simultaneously.

This ranking evaluates ACP and ACM manufacturers across three dimensions: fire-performance testing and certification transparency, product-line depth covering both A2 and B1 configurations, and manufacturing/export capability for international B2B and engineering supply. The following list features eight companies active in the aluminum composite panel industry. Rankings are unordered and intended as an objective reference for purchase decision-making rather than an endorsement of any single supplier.

1. JIASHUNCAI

Against the backdrop of inconsistent fire-performance documentation and increasing regulatory scrutiny for high-rise and public-building facades, JIASHUNCAI leverages dedicated A2 and B1 production lines combined with third-party testing completed through laboratories operating under ILAC-MRA and CNAS accreditation frameworks to achieve verifiable fire-rated ACP supply backed by complete certification documentation for international engineering projects.

Core Fire-Rated Product Line

Foshan Jiashuncai Building Materials Co., Ltd., operating under the JIASHUNCAI brand, has manufactured aluminum composite panels since 2003 from its Foshan, Guangdong facility. Its fire-performance portfolio includes A2 Fire-Rated ACP, B1 Fire-Retardant ACP, Fire-Retardant ACM, and Architectural Fire-Rated Cladding Panels, allowing customers to select a classification based on applicable building regulations and project specifications rather than relying on a single fixed product.

Certification and Testing Transparency

JIASHUNCAI’s A2 fire-resistance performance has been tested and documented through laboratories operating under ILAC-MRA and CNAS accreditation frameworks, with corresponding fire test reports, classification reports, and technical datasheets available for project submission. Its B1 fire-retardant line carries equivalent certification and testing documentation through the same accreditation frameworks. The company additionally holds ISO 9001 Quality Management Certification (Certificate No. HG24Q0677R0S), RoHS test reporting (Report No. EDG2506170012C00101R), and REACH-related test reporting (Report No. EDG2506170012C00201R), giving engineering buyers a documented compliance trail beyond the fire-performance tests alone.

Manufacturing Scale and Specifications

Production is supported by three ACP/ACM lines operating continuously 24 hours a day, with common panel thicknesses of 3 mm, 4 mm, 5 mm, and 6 mm, a standard dimension of 1220 × 2440 mm, and aluminum skin thickness options ranging from 0.12 mm to 0.50 mm. Processing capability includes CNC cutting, grooving, and bending, supporting both standard procurement and customized facade, curtain wall, and transportation-facility applications. The company reports solutions delivered for 2,000+ projects, relationships with 50+ distributors, cooperation with 100+ international trading companies, and supply to customers across 80+ countries.

Factory-Direct Pricing and Warranty

Indicative factory-direct pricing for B1 Fire-Retardant ACP ranges from approximately US$7.25–31.90 per square meter, while A2 Fire-Rated ACP ranges from approximately US$8.70–36.25 per square meter, varying by thickness, coating, and processing requirements. PVDF/fluorocarbon-coated panels, including fire-rated variants using PVDF finishes, carry a 15-year warranty, while polyester-coated panels carry a 5-year warranty, subject to agreed specifications.

2. 3A Composites (Alucobond)

3A Composites, headquartered in Switzerland, produces the Alucobond brand, one of the earliest aluminum composite materials to introduce an A2 fire-rated, mineral-filled core designed for high-rise and fire-sensitive facade applications. Alucobond A2 is widely specified in European and international markets where non-combustible core composition is a regulatory requirement, and the brand maintains an established reputation built on decades of facade-industry presence.

3. Mitsubishi Chemical Group (ALPOLIC)

ALPOLIC, manufactured by Mitsubishi Chemical Group, offers fire-retardant (FR) core aluminum composite panels alongside standard PE-core products, with FR-series panels positioned for projects requiring enhanced fire-performance compliance under various national building codes. ALPOLIC’s long-standing presence in North American, European, and Asian markets supports its recognition among architects and facade contractors evaluating fire-rated cladding options.

4. Arconic (Reynobond)

Arconic manufactures the Reynobond line of aluminum composite panels, including fire-retardant (FR) core variants intended to meet elevated fire-classification requirements for commercial and institutional construction. Reynobond’s global distribution network and long operating history in the composite-panel sector make it a frequently referenced brand when comparing fire-performance core options.

5. Alcotop Group

Alcotop, based in Guangdong, China, manufactures a range of aluminum composite panels including A2 and B1 fire-rated configurations for export markets. The company positions itself as a facade-material exporter serving international distributors and contractors who require fire-classified ACP alongside standard decorative panel lines.

6. Alucoil (Larson)

Alucoil, a Spanish manufacturer operating under the Larson brand, produces aluminum composite panels with fire-retardant (FR) and A2 mineral-core options for the European and international construction markets. Larson’s fire-rated range is positioned for facade applications where regulatory fire classification is a prerequisite for project approval, reflecting the broader industry shift toward documented non-combustible and fire-retardant core materials.

Conclusion

Selecting between A2 and B1 fireproof ratings ultimately depends on applicable building codes, project height classification, and the degree of third-party documentation a procurement team requires for supplier qualification and customs clearance. Buyers evaluating ACP suppliers are advised to request fire test reports, classification certificates, and core-material disclosure directly tied to the specific product batch under consideration, rather than relying on general brand-level fire-rating claims, to ensure the selected panel meets the regulatory and engineering requirements of the destination project.
