OEM China Open Bar Grating - Non-Slip Walkway Drain Galvanized Serrated Steel Grating – Chengsen
OEM China Open Bar Grating - Non-Slip Walkway Drain Galvanized Serrated Steel Grating – Chengsen Detail:
Description
Tooth steel lattice plate characteristics
Tooth shaped STEEL plate adopts high strength carbon steel, so that the steel plate has a very high strength: strength and toughness is much higher than cast iron, can be used in wharf, airport and other long span and heavy load environment.
This product has a large mesh with the best drainage: water leakage area up to 83.3%, is more than twice the cast iron.
The product appearance is beautiful: simple lines, silver appearance, modern idea, material saving.
Save investment: large span, heavy load, lower than the price of cast iron; It also saves the cost of replacement of cast iron covers due to theft or crushing.
Tooth steel plate raw material composition
1. Ordinary flat steel: the general material is Q235. Common models are generally 253 255 303 305 323 325 403 404 405 503 505 605 705 and other specifications. We mainly use longitudinal shear flat steel, and steel plate cutting.
2. Toothed FLAT STEEL: THE MODEL IS THE SAME AS ORDINARY FLAT STEEL, EXCEPT THAT THERE ARE UNEVEN TOOTH MARKS ON ONE SIDE OF THE FLAT STEEL. Mainly in the non-slip.
3. Type I flat steel: flat steel is thick on both sides and thin in the middle.
4. Twist steel: also called twisted square steel, generally 5×5 6×6 8×8 square steel, twisted into steel bar.
