(2) Do not stack with acid, alkali, Q345B square tube salt, Q345B square steel tube forming process knowledge, cement and other materials that are corrosive to Q345B cold drawn square tube in the warehouse.Different types of Q345B cold drawn square tubes should be stacked separately to prevent confusion and prevent contact corrosion;
(3) Large section steel, rails, steel plates, large diameter Q345B cold drawn square pipes, forgings, etc. can be stacked in the open;
(4) Small and medium-sized steel, wire rod, steel bar, Q345B square tube, Q345B cold-drawn square tube, steel wire and wire rope, etc., can be stored in a well-ventilated material shed, but must be top and bottom pads;
(5) Some small Q345B cold-drawn square tubes, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled Q345B cold-drawn square tubes, various cold-rolled, cold-drawn Q345B cold-drawn square tubes and high prices, Q345B square tubes Easily corrosive metal products can be stored in storage;
(6) The warehouse should be selected according to geographical conditions.Knowledge of the two forming processes of Q345B square steel pipes generally adopts ordinary closed warehouses, i.e. warehouses with roofs and walls, tight doors and windows and ventilation devices;
(7) The warehouse is required to be ventilated on sunny days, shut down to prevent moisture on rainy days, and always maintain a suitable storage environment
2. Reasonable stacking, put first
(1) The principle of stacking is to ensure that the stacking is stable and safe, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold dr
