Both hot rolled flat bar (higher cost, better mechanical ability and smooth edge) and slitted flat bar(lower cost, shark edge) are widely used for further processing at destination. Both can be made in flat or serrated on one side.

We are also developing cold rolled flat bars from slitted bars, which has better mechanical ability, medium cost and accurate tolerance.

Materials can be according to Q235, A36, S235JR or equivalent. However, China standard Q235 is widely used with low cost and quality stability.

To ensure quality stable, most of standard grating panels will be processed by pressure welding machine made from Wuxi Weihua Electric Welding Manufacture Co.Ltd. Who is most reputable manufacturer in China.
