1050 Aluminum checker(tread) plate belongs to the non-slip aluminum sheet series. Among all the aluminum checker plates, the 5 bar aluminum checker plate is the most anti-slip one. The surface is covered with five parallel uneven patterns. According to the data, the included angle between two five patterns is 60°-80°, and each stripe is 30mm or 40mm long, which means that the contact between the object and the 5 bar aluminum checker plate will produce strong friction resistance.
