The strip is rolled by process.
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
Also, I do not know whether you are welding stainless steel or iron, the novice can press the method to do, but ripe workers are visual, direct welding, of course, visual accuracy will always be a little worse,
Q:How can we see is galvanized steel or wood
The first dip galvanized pipe is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency. Or the cold formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
Q:25-30mm drill pipe steel, to drill a lot, need what equipment
purposeApplicable to steel structure, shipbuilding, equipment manufacturing, equipment installation, bridge engineering, wind power generation, oil drilling platform, power construction, railway manufacturing and other fields.
Q:The moment 2mm thick galvanized square steel tube using what welding methods
Galvanized square tube adopts gas shielded welding, conventional J50 gas shielded welding wireArgon arc welding galvanized square pipe, zinc burning more severe, not recommended
Q:Glass partition, square box outsourcing 1mm thick stainless steel, glass middle is how to set the quota
In this case, a metal frame must be used to hold the glass and then bolt it into the wall!
Q:As for steel structure steel, how appropriate
The size of the material is strongly related to the load on your floor, and the roof material and column size are also related to your span and the local Blizzard loads. You can choose the size of the material according to the local conditions.
Q:The difference between cold and hot galvanized steel hollow where
Cold rolling process is: the strip through the mold, pipeline bending forming, and then through the automatic welding, the welding joints, and then polished, galvanized, also called seamed tube.
