Model:

Export area:North America Central-South America ASIA Europe Africa Oceania

Introduction:
The latest information of flat steel flat flat steel bar and flat flat steel is a rectangular solid hot-rolled strip flat rolled with a rectangular cross section rolled from the ordinary carbon structure. According to the different production methods and appearance, it is divided into hot-rolled flat steel, embossed flat steel, embossed flat steel, cold drawn square steel. The hot rolled flat steel produced and processed by the company is rolled by the repeated rolls of the large-scale automatic assembly line hot rolling mill, not only the size and length can be obtained, but also the structural density of the flat steel itself can be increased, so as to improve the mechanical properties of flat steel, the strength and toughness of the flat steel are improved. The yield point of hot rolled flat steel is 235, tensile strength is 390, elongation is 26, material and mechanical properties meet the national and customer standards. The hot rolled flat steel of the company is stable, the product surface is flat, no skin, no crack, no burr, r angle radian uniform nature, welding, drilling, bending, twisting and other processes can be applicable to a variety of industries.

Model:

Export area:North America Central-South America ASIA Europe Africa Oceania

Introduction:
The hot dip galvanized angle steel supply company adopts the advanced hot dip galvanizing line technology, the product surface is bright, no leakage, no scars and drip, zinc layer is even, strong adhesion, the material meets the national standards, has a certain corrosion resistance.
The galvanized layer of the hot dip galvanized angle steel and the steel is metallurgical bonding, become a part of the steel surface, so the durability of the coating is more reliable; The toughness of the coating is strong, the galvanized layer forms a special metallurgical structure, which can withstand the mechanical damage caused by the transportation and use; Therefore, our company's hot galvanized angle steel has been well received by the majority of users throughout the country.

Hot dip galvanized I - beam

Export area:North America Central-South America ASIA Europe Africa Oceania

Introduction:
The hot - dip galvanized I - beam is also called hot - dip galvanized steel beam, which is a long steel bar with cross section. The hot - dip galvanized I - beam is a narrow - sided, narrow - side I - beam made of the inner side of the leg, which is made of hot rolling. The size of the waist height ( h ) * leg width ( b ) * waist thickness ( d ) of the mm number indicated, such as " labor 140 * 80 * 5.5 ", that is, the waist height of 140 mm, the leg width is 80 mm, the waist thick is 5.5 mm hot galvanized steel I - beam. Its specifications can also be expressed in the model, the model represents the height of the height of the number of centimeters, such as hot - dip galvanized steel 14 #. I - beam with the same height, if there are several different legs width and waist thickness, add a, b and c to the right of the model, such as 22a #, 22b #, etc
Standard for the implementation of hot - dip galvanized steel: GB / t 13912eyes - 2002 GB / t706 - 1988
Hot dip galvanized I - beam material: Q235, q235b
Hot - dip galvanized steel specification: 10 # - 63 c #

Hot - dip galvanized square steel tube

H.S CODE:
Model:

Export area:North America Central-South America ASIA Europe Africa Oceania

Introduction:
The hot galvanized square pipe supplied by our company adopts advanced hot dip galvanizing line process, the product surface is bright, no leakage, no scars, no drop, uniform zinc layer, strong adhesion, and the material is in accordance with national standards, with a certain corrosion resistance.
Production process: before the hot dip galvanized square pipe enters the hot dip galvanizing production line, the selected flat and there is no square tubes are first sent to the pickling workshop, and the iron oxide scale and floating rust on the surface of the hot dip galvanized square pipe are removed by soaking with acid or acid. After 2 times of acid pickling, the pickling time according to the different raw materials of the square tube square tube is different, roughly in 30 - 50 minutes, when the surface floating rust and oxide skin of the square tube are thoroughly washed away, immerse and wait for galvanized in the water box immediately, so as to prevent the square tube square tube re - oxidation. after the second clean water washing, the drying bed drying, and then immerse the hot - dip galvanized square tube into a temperature of 460 for hot dip galvanizing operation, and finally, according to the customer's different requirements, dry and cool hot galvanized square pipe for oiling or passivation treatment. This method of production of galvanized finished products, anti-corrosion ability is significantly improved. In the general environment, the antirust thickness of hot dip galvanized square steel can be kept for more than 50 years without repair. In urban or offshore areas, the hot dip galvanized rust layer can be maintained for 20 years without being repaired.

Hot dip galvanized channel steel

H.S CODE:
Model:

Export area:North America Central-South America ASIA Europe Africa Oceania

Introduction:
The domestic hot dip galvanized steel industry faces a severe test this year, with the iron and steel prices low, the processing profits of hot dip galvanized channel steel has been compressed, some small hot dip galvanized manufacturers are close to failure, the former production also can be small and medium-sized manufacturers, the production is less than last year's 2 / 3, due to the chaos of the galvanized channel steel market, some of the business price competition, promote the current market profit more transparent. " cost savings" is part of the manufacturers in " troubled times"
Hot dip galvanized channel steel
The law of the survival of the hot dip galvanized channel steel " good and bad ", the product after-sales service problem is to be solved by manufacturers and manufacturers effective solutions.
In fact, for the hot dip galvanized steel market, the most concerned is the corrosion resistance of hot dip galvanized. The ratio of " passivation solution" is the " magic weapon" for each zinc plating factory to survive. Without the standard formula, the corrosion resistance of the hot dip galvanized channel steel will be greatly reduced.
