Fireproof Base Board
Class A1 Non-combustible · The Base Layer for Partitions & Ceilings
Magnesium crystal fireproof base board is an inorganic fire-resistant board made primarily from magnesium cementitious materials through modified pressing and curing. Classified Class A1 non-combustible under GB 8624-2012, it is lightweight, high-strength, moisture-proof and formaldehyde-free — widely used as the base layer for partitions, ceilings and fire-rated constructions.

FAQ
What is the fire rating of magnesium crystal fireproof board?+
Our fireproof base board reaches Class A1 non-combustible under GB 8624-2012 — the highest classification, meaning no flaming combustion and no flame spread. Batch-specific third-party test reports are available on request.
What is the price of Class A1 fireproof board?+
Pricing varies with thickness, specification, quantity and destination. Submit an inquiry with quantity and project details via our project inquiry form — formal quotations are provided within 24 hours; dealers receive regional pricing.
Magnesium board vs fiber cement/calcium silicate board?+
Both are inorganic fire-resistant boards. Magnesium board uses modified magnesium cementitious materials, offering controllable density, good screw-holding and toughness with no asbestos; calcium silicate board is silica-lime based. See our comparison article for selection guidance.
Is it moisture-proof? Can it be used in bathrooms and basements?+
Yes. The board is moisture-proof and suitable for humid base-layer applications such as bathrooms, basements and kitchens. For permanent water immersion or direct exterior exposure, use the recommended waterproofing system and consult our technical support.
How is it installed? Is wet construction required?+
Dry construction: the boards can be sawed, nailed and drilled, installed on light-gauge steel or timber frames with joint treatment per standard details — no mortar work, no curing time, and high installation efficiency.
Which international standard does the export product reference?+
Export documentation cross-references GB 8624-2012 with EN 13501-1 (European fire classification); Class A1 corresponds to Euroclass A1. Project-specific test and certification documents can be provided per destination requirements.
