ss304 ss316 stainless steel grate drain grill stainless steel grating trench cover plate

welding slag or scar left in the welding process. 2. Material and specification of stainless steel grating plate: According to the material, it can be divided into: 201 high-quality stainless steel (weak corrosion resistance, low price), 316 high-quality stainless steel (strong corrosion resistance, high price), 304 high-quality stainless steel (general corrosion resistance, most commonly used, recommended). 3. Surface types: plane type, tooth type and I type, with more than 200 specifications (different protective treatment can be carried out on the surface according to different use environment). 4. Grid plate type: plug in type, ordinary type 5. Common hole types of stainless steel grating plate: 30 * 100 mm, 40 * 100 mm, 50 * 100 mm, 30 * 50 mm, etc As stainless steel itself has a good anti-corrosion performance, so stainless steel grating step generally does not need surface treatment. Special requirements for surface polishing surface treatment. 6. Features of stainless steel grating plate: (1) It has the advantages of light weight, high strength, large bearing capacity, economical material saving, ventilation, modern style and beautiful appearance. (2) It is skid resistant, safe, easy to clean, easy to install and durable. (3) Compared with other gratings, it has better anti-corrosion effect, but its cost is nearly three times more than ordinary steel gratings. 7. Use of stainless steel grating plate: Power plant, chemical plant, oil refinery, iron and steel plant, machinery manufacturing plant, shipyard, cement plant,

medicine, food processing plant, bridge engineering, municipal engineering project, etc. It is widely used in all kinds of factories and engineering projects at home and abroad.
