According to the report of the Economic Herald, under the continuous regulation and control of the policy, the domestic steel price fell. The rebar has dropped from a high of about 6,200 yuan/ton in May to about 5,000 yuan/ton now, a drop of more than 1,000 yuan.

Advantages of Using Galvanized PipesGalvanized (GI) pipes, widely applied across industrial and construction sectors, offer significant benefits in corrosion protection, mechanical durability, service lifespan, cost efficiency, and environmental performance. The following summary outlines these adva

Recently, the Shandong Provincial Development and Reform Commission issued a notice on matters related to the ultra-low emission differential electricity price policy for iron and steel enterprises. If it is transformed, all the electricity purchased online (market-oriented transaction electricity, electricity purchased by power grid companies) will implement the electricity price increase policy. If all ultra-low emission transformations are completed, there will be no price increase for electricity. The notice will be implemented from July 1, 2022 and will be valid until December 31, 2026.

The common hot-dip galvanized steel products include galvanized steel sheet and strip, galvanized steel wire and wire mesh, galvanized steel pipe, galvanized section steel and structural parts, galvanized pipe fittings (malleable iron pipe fittings), galvanized parts, fasteners, galvanized device pr

Plating Definition

(1) Normal spangle coating

During the normal solidification process of the zinc layer, the zinc grains grow freely and form a coating with an obvious spangle shape.

(2)Minimized spangle coating

During the solidification process of the zinc layer, the zinc grains are artificially restricted to form the smallest possible spangle coating.

Corrugated sheet is also called profiled sheet, which is a profiled sheet that uses color coated steel sheet, galvanized sheet and other metal sheets to be rolled and cold-formed into various corrugated sheets.

Galvanized steel pipe connection method: thread, welding.

Roll groove connection

(1) Cracking of rolling groove welds

1. Flatten the inner wall welding rib of the pressure groove part of the nozzle to reduce the rolling groove resistance.

2. Adjust the axis of the steel pipe and the rolling groove equipment, and require the steel pipe and the rolling groove equipment to be level.

3. Adjust the grooving speed, the forming time of the grooving cannot exceed the specified time, and apply force evenly and slowly.
