It relies on an ultra-stable alloy passivation film to resist continuous chemical liquid immersion, high-concentration acid-alkali splashes, and volatile corrosive vapor erosion, maintaining complete structural integrity and stable load-bearing performance in long-term strong corrosion service.
In global chemical industrial classification, acid-alkali resistant grating is defined as extreme chemical corrosion dedicated grating, the only reliable structural flooring for core strong-corrosion zones including electroplating production lines, industrial acid washing workshops, chemical reaction tank surrounds, and reagent storage areas, filling the market gap of professional grating for concentrated acid-alkali working conditions.
Why Ordinary Industrial Gratings Fail in Strong Acid-Alkali Environments
Most conventional grating products are designed for general industrial environments and cannot adapt to extreme strong chemical corrosion, resulting in rapid performance attenuation and scrapping.
Coated Carbon Steel Grating Chemical Dissolution Failure
HDG galvanized, painted, powder-coated, and bitumen-coated gratings depend on external protective layers. Strong acid and alkali media will chemically react with and dissolve the coating layer, causing blistering, cracking, and peeling in a short time. Once the substrate is exposed, rapid rusting and structural corrosion occur, completely losing load-bearing and anti-corrosion functions in strong chemical workshops.
Ordinary Stainless Steel Grating Welding Intergranular Corrosion
Conventional 304/316 stainless steel gratings adopt ordinary high-temperature welding, which causes carbon precipitation and welding sensitization. In strong acid-alkali environments, welding joints produce severe intergranular corrosion, leading to local cracking, loose structures, and overall failure, unable to support long-term strong corrosion industrial operation.
Mild Corrosion Grating Performance Redundancy & Deficiency
Salt-fog and sewage corrosion-resistant gratings are only suitable for mild composite corrosion environments. Facing concentrated acid-alkali splash and immersion, their passivation film will be rapidly destroyed, unable to resist extreme chemical erosion, resulting in accelerated metal corrosion and structural damage.
316L Anti-Sensitization Technology: Core Acid-Alkali Resistant Mechanism
The extreme chemical corrosion resistance of acid-alkali resistant grating comes from exclusive 316L low-carbon material formula and professional welding technology, forming a stable anti-corrosion system that no ordinary grating can replicate.
316L Ultra-Low-Carbon Stainless Steel Material Advantage
316L low-carbon stainless steel has ultra-low carbon content, effectively avoiding carbon precipitation during welding and eliminating welding sensitization. The added molybdenum alloy element greatly enhances resistance to concentrated acid, strong alkali, and chemical vapor erosion, with chemical stability far exceeding ordinary stainless steel materials. It will not produce chemical reaction or structural deterioration when exposed to various concentrated industrial chemical media for a long time.
Full Penetration Anti-Sensitization Fusion Welding
Adopt low-temperature precise fusion welding process dedicated for stainless steel, which controls welding temperature accurately, avoids local alloy component damage and precipitation, and ensures uniform anti-corrosion performance of welding joints and base material. The full penetration welding forms an integrated seamless metallic structure, without welding gaps or corrosion dead corners, achieving overall consistent strong acid-alkali resistance.
Ultra-Stable Self-Healing Passivation Film Protection
The 316L alloy surface forms a dense and stable chromium-molybdenum passivation film, which is insoluble in concentrated acid and alkali solutions. The passivation film has automatic self-healing ability; slight surface scratches can be quickly repaired to form a new protective layer, permanently isolating strong chemical media and realizing long-term stable anti-corrosion performance.
