Steel lattice plate is a kind of orthogonal combination of bearing flat steel and cross bar according to a certain distance.

An open plate steel member fixed by welding or pressure locking.

According to the production method is different, mainly divided into pressure welded steel grid and compressed steel grid. Zinc steel grid and steel grid after the production, to carry out anti-rust treatment. There are hot dip galvanizing and electric galvanizing 2 kinds. Hot dip galvanizing standard is: GB/T 13912-2002 hot dip galvanized steel parts technical requirements and experimental methods As a new material, new products are being increasingly widely used, its more superior performance and good price-performance ratio shows its application prospects. This paper discusses the performance of steel grid, economical selection of steel grid and comprehensive technical and economic analysis. In metallurgy, mining, petroleum, electric power and industrial fields as well as some civil fields, steel grid as a new building materials are being increasingly widely used.
