What kind of material test is necessary for steel structure engineering?
The weld welding coating raw material of the fastener chemical anchor bolt pull-out test anchor bolt should not do ah
All materials used, such as various steel plates, steel tubes, H steel, square tubes, etc.. Purlin and color steel plate generally do not do, do bulk insulation cotton.
The test of high strength bolt connection must be done, and the anchor bolt needs to be made of raw material.
Steel structure engineering needs the steel structure raw material (steel plate) test, testing, welding test, welding seam without damaging the ball and a bolt ball test, fire coating test, deflection detection of these almost.
