There are several materials for grilles

Wiki Article

Aluminum alloy grilles are currently the most widely used material. They have the characteristics of light weight (density of about 2.7g/cm³), high strength (tensile strength can reach 300MPa), and corrosion resistance. They are produced by die-casting process, with low cost and strong plasticity.

They are suitable for scenes such as building doors and windows, exterior wall decoration, etc. Galvanized steel plate grilles provide anti-corrosion protection with a galvanized layer (zinc layer thickness ≥ 20μm), and perform well in industrial fields such as chemical industry and electric power, especially in marine environments. The corrosion resistance of salt spray is outstanding. Stainless steel grilles (commonly used 304/316 materials) have higher corrosion resistance (acid and alkali pH range 1-14) and strength, and are widely used in fields with high hygiene requirements such as food and medicine.

Carbon steel grilles have the strongest bearing capacity (allowable load can reach 5 tons/m²), but they need to be galvanized (zinc layer ≥ 80μm) or painted to improve corrosion resistance, which is suitable for heavy-load occasions such as parking lots. Hebei Runlong Environmental Protection Technology Co., Ltd. provides customized services for gratings made of various materials.

It can recommend suitable solutions based on specific application scenarios (such as corrosion resistance and load-bearing requirements), and its professional technical team can assist in the selection.
