Another booth price of cement board activities, under strict conditions girders, after laying a layer of steel grid on the checkered, with fine steel plus concrete poured to a thickness of no more than 5 cm of the floor. Dongyang sun of Steel Materials Co., to introduce you to check the connection surface, remove rust, burrs and oil 1, check the connection member surface, the friction surface machining high-strength bolted joints can be sandblasting, shot blasting and sanding methods. Anti-slip coefficient processed should meet the design requirements. 2, the friction surface has surface rust remove without burrs and oil.
