China GI Steel Props Acro Jack Scaffolding Prop For Scaffolding Slab
GI steel props for scaffolding slab is frequently used in formwork and construction to support the floors, ceilings, bridges and beams. With its high load-bearing capacity, it is popular on temporary supports during building repair or alteration work. The advantages are easy to use and time-effective to install, also lower cost. In construction, steel props is used as vertical support in scaffolding as below situation, such as: removing walls, making holes, temporary support for ceiling, beams and so on. Quality is the priority especially in construction safety. Our factory has more than 15 years experience in steel pipes and scaffolding products. We have our own pipe factory, galvanization factory and scaffolding factory, which help us control the quality from tube material, tube sizes, prop welding and packing. All for the better quality and safety construction.
China Scaffolding Cold Rolled GI Pipes
The GI pipes, also called pre galvanized steel pipes, are cold rolled round pipes made by galvanized steel strips. The GI pipes are widely used in scaffolding construction, greenhouse pipes, fence pipes, agricultural pipes and other areas. There are two kinds of galvanization: hot dipped galvanization and pre galvanization. Pre galvanization is also declined to hot dipped galvanization, which the zinc coating formed by immersing steel pipes into the melting zinc. The difference between hot dipped galvanization and pre galvanization pipes is that pre galvanized pipes are made by galvanized steel coils directly. While hot dipped galvanized pipes are made by black steel coils into black pipes at first, then immerse the black pipes into zinc pond. Tianjin Friend Steel Pipe CO.LTD has more than 15 years experience in steel pipe, we have always tried our best to provide high quality pipes for you.
SCH 40 Standard Galvanized Steel Pipe
Hot-dipped galvanized treatment : 1. Uniformity of galvanized coating: the steel tube sample shall not turn red (copper-plated color) after being continuously impregnated in copper sulfate solution for 5 times. 2, surface quality: the surface of galvanized steel pipe should be a complete galvanized layer, there should be no unplated black spots and bubbles, there is not much rough surface and local zinc tumor is allowed to exist. 3, galvanized layer weight: according to the requirements of the buyer, galvanized steel pipe can be made of zinc layer weight determination, the average value should not be less than 500g/ m2, any sample should not be less than 480g/ m2.

Schedule 40 Carbon Steel Pipes
Welded carbon steel pipe is the most economical and durable ways to connect the pipes together. The raw material used for welded steel pipe is steel plate or strip steel. According to different standards and requirements, there are many kinds of steel strip materials. The most commonly used material is Q195-Q345: the Q195 similar to a283 GR.B, 040A10, SS330, SPH the Q235 similar to a283 GR.B, 080A15, the Q345 similar to a737 GR.B, SS400, S235JR, SKT500 Welded carbon steel pipes is widely used in fluid pipelines, power plants, structural tubes, high and low pressure boiler tubes, scaffold tubes, pharmaceuticals and construction.
Light Duty Adjustable formwork Steel Props Scaffolding Acro Jack
There are two kinds of steel props, heavy duty and light duty steel props for different loading capacity. Also various adjustable length can be available. Then how to test the quality of steel props when you purchase the products. Firstly, the raw material of the steel tubes. There are various steel coils for tubes such as Q195, Q235 and Q345 with different mechanical performance. Secondly, the welding parts is significant. The welding lines should be smooth and totally melt with the plate. It’s important to check the welding lines in case of incomplete welding and air holes. Thirdly is the surface. Painted, galvanized, powder coated surface are available. Painting is easy to fall off after cracking while the galvanized ones are better on anti-rusting. Powder coated surface is much better than painted, but the cost is much higher.
JIS STK500 Galvanized Steel Pipes
JIS STK500 galvanized steel pipes： STK500 is a Japanese material brand, and its mechanical properties are as follows: tensile strength N/mm 500 yield N/mm 355. Japanese industrial standard for carbon steel tubes used in earthwork, construction, scaffolding, piles, and other installations. Hot-dipped galvanized : Durability: in a suburban environment, the standard galvanized rustproof thickness can be maintained for more than 50 years without repair;In urban or offshore areas, the standard hot dip galvanized rust barrier can be maintained for 20 years without repair;
BS1387 Galvanized Iron Water Pipes
Galvanized steel pipes have nice performance in anti-corrosion. Gi pipe can be divided into hot galvanized and pre galvanized mainly. Hot galvanized pipe is thick in galvanization layer, so it behaves much well in corrosion resistant. While pre galvanized pipe is much economical. Surface quality of galvanized steel pipe should have a complete galvanized layer, there should be no unplated black spot, there is not much rough surface and the existence.
