The steel wire mesh produced by wire mesh factories in China meets the quality standards: steel wire mesh in shape and steel wire welding in customization. The shape and size of the reinforcing bar net shall be determined by negotiation between the two parties according to the design and construction requirements.
The shape grid steel bar is in two directions, but it can lead to the same shortcut in the same direction and diameter interval. The second time interval, the production of cold-rolled HRB400 grade steel bar under steel mesh rib or hot-rolled grade steel bar under steel rib should be adopted in crb550, and the production of cold-rolled grade steel bar under steel rib may be used in cpb550. Note: The technology of mesh reinforcement should meet the national standard requirements of gb/t-1499.3 2002.
The specifications of the steel mesh shall meet the following requirements: the length of the mesh shall be 12 meters and the width shall not exceed 3.3 meters. The most suitable spacing for making steel mesh in the direction of trolley is 100mm, 150mm and vertical production; the steel bar with 200mm spacing should have the ability to remedy the'precipitation 10mm'for all drainage. The grid is longitudinal stiffened and can be realized in the form of stiffening. Double-layer steel bar, rain spacing stress steel bar should not be more than 10 mm.
Bar diameter: cold-rolled strip light drawing or steel bar surface length of 12 mm and steel bar, cold-added 4:4 steel bar worker diameter in the 12 mm range of 0.5 mm force steel bar driver 5-12 mm; hot-rolled ribbed steel driver's draught is 6-16 mm. The reinforcing bar strength of steel mesh should not be lower than the standard strength. The strength of cold-rolled ribbed steel bar and cold-drawn steel bar with 95% guaranteed rate is expressed by the standard port FSTK of limit specification, and the strength is determined. The strength standard value of hot-rolled ribbed bar is determined according to fyk and grabbing rate.
