Q1: How do we guarantee the quality of our products?

A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:How big is the channel used for the 4 metre span?
The specifications are expressed by the height of the waist (H) * leg width (b) * waist thickness (d), such as "work 160*88*6", which means that the waist height is 160 mm, the width of the leg is 88 mm, and the thickness of the waist is 6 mm. The specifications of I-beam can also be expressed by type. The model indicates the height of centimeters, such as 16#.
Q:What is the difference between steel tubes such as channel steel or square tube?
The channel for supporting, steel used for machining shaft and pin and the like, used to make steel keel frame and embedded parts in civil engineering, steel used for heavy support for small angle support or molding square tube used for various doors and windows, modification.
Q:8# what's the size of the channel steel?
8# channel steel size 80*43*5mm, that is, height 80mm
Q:What calculates the endurance of a channel?
You see the position of the connection, the size of the material and some other factor, such as: channel three directions can be put, namely: upright, upward, lying and N, which support: two ends simply supported and fixed at both ends, and the other end of the cantilever end of the cantilever, the cantilever simply supported at both ends.......
Q:What is the difference between channel steel and angle steel?
The upper and lower leg channel width is equal, the section is in a groove shape, said channel specification method is based on the height (mm) (mm) * * legs wide waist thickness (mm) in the form of a rectangular section angle is basically the same, on both sides of the thickness and width of steel, steel specifications method is usually in terms of edge width * thick edge.
Q:Is it OK to use the channel steel to do the Overhanging Scaffold? Is there any difference between the cantilever scaffold made of I-beam and channel steel?
Yes, both I-beam and channel steel have specifications and models. As long as they can meet the load requirements, there is no difference between them.
Q:Formula for section modulus of channel steel
Section modulus Wx and Wy of channel steel are the same as those of hot-rolled steel (including angle steel and I-beam). They only need to be checked on the ready form.
Q:What are the lengths of the channel factory?
The delivery length of channel steel is divided into two kinds: foot length and double foot length, and the allowable difference is stipulated in the corresponding standard. The length of domestic channel selection range according to specifications, divided into 5 - 12M, 5 - 19m, 6 - 19m three. The length of imported channel steel is generally 6 - 15m.
Q:What kind of low carbon steel and medium carbon steel are they?
Low carbon steel is limited in use due to its low strength. Increasing the content of manganese in the carbon steel and adding some alloying elements such as vanadium, titanium and niobium can greatly improve the strength of the steel. If the carbon content in the steel is reduced and a small amount of aluminum, a small amount of boron and carbide are added to form the element, the super low carbon bainite can be obtained, and its strength is very high and good plasticity and toughness can be maintained
Q:What is the difference between channel steel and C steel?
Channel steel is produced by hot rolling, supplied directly by iron and steel works, and thicker
