Q195-Grade B Galvanized Square Tube

PRODUCT DESCRIPTION

Galvanized Square Steel Pipe is a general term for square steel pipes and rectangular pipes, that is, steel pipes with equal side lengths. It is made of strip steel through process treatment and rolling. Generally, the strip steel is unpacked, leveled, crimped, welded into a round tube, rolled into a square tube, and then cut to the required length. Usually 50 pieces per pack. Also known as square, rectangular cold-formed hollow section steel, referred to as square tube, rectangular tube.
1. Classification of square and rectangular tube production process
Square rectangular tubes are divided into hot-rolled seamless square steel tubes, cold-drawn seamless square tubes, extruded seamless square tubes and welded square tubes according to the production process. Welded square tubes are divided into: (a) arc welded square tubes, resistance welded square tubes (high frequency and low frequency), gas welded square tubes and furnace welded square tubes; (b) straight seam welded square tubes and spiral welded square tubes according to welding points Minute
2. Material classification of square and rectangular tubes
Square tubes are divided into plain Carbon Steel square tubes and low alloy square tubes according to their materials. Ordinary carbon steel is divided into Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc.; low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.
1. Liaocheng Changyi is committed to long-term development and creates high-quality products and services. Have the same pursuit of quality and service, stable and powerful, to maximize the consistency and stability of materials, product appearance and internal quality;
2. Galvanized square steel pipes and rectangular steel pipes are divided into the following grades
Q195—B grade, SS330, SPC, S185Q215—C grade, CS B type, SS330, SPHC, Q235—D grade, SS400, S235JR, S235JO, S235J2, Q345—SS500, ST52, S355JR
3. The galvanized layer can be customized, up to 280 grams.
4. The purity of zinc wire is 99.99%, and the zinc content is high, so that the weld seam of the pipe does not rust.
5. The diameter of zinc wire is 1.5mm, which has a good protective effect on welding.
6. No corrosion in the salt spray test for at least 8 hours.
7. In the passivation process, we have our own invention patent - automatic spraying system of galvanized pipe passivation solution, which ensures uniform adhesion, high passivation efficiency and beautiful appearance.
