Q1: What makes stainless steel stainless?

A1: 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.

Q2: Can stainless steel rust?

A2: 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.

Q3: How do you package the angle steel when shipping?

A3: All goods are packed in bundles with steel strips and shipped by container or break bulk.

Q:What should I do with a screw or nut or bolt on the ramp?
On the inclined plane, screws or nuts or bolts should be avoided and solved by changing the design method, because it not only affects the force of the fastener, but also causes difficulties in drilling
Q:Standard for channel 20
Can check the hot-rolled ordinary channel GB707-88
Q:Is it better to cast a pipe or a channel steel?
CastAdvantages: strong, relatively sound insulationDisadvantages: self importantMethods: in the load-bearing wall planting steel, tied with steel, formwork, pouring 10~12cm, waiting for about 28 days molding (summer time is slightly shorter)Watch out:A, pay attention to the proportion of cement and yellow sand and water, the conditional best to buy finished concreteB, when the beam bar open, found in the reinforced beam, the best anchorage reinforcement and ring beam reinforced with imported glue stick, anchorage length is about 13cm;C, after planting tendons, use concrete pouring, pay special attention to the concrete to fill the hole, and side shock side irrigation;D, too large span of the room, it is best not to use cast-in-place.
Q:What kind of steel products are there, such as channel steel, angle iron and so on?
Screw thread steelThe general length of thread steel is 9m and 12M, 9m long thread is mainly used for road construction, and 12m long thread is mainly used for bridge construction. The thread specification range is generally 6-50mm, and the state allows deviations. Thread steel according to the strength of HRB335, HRB400, HRB500, three models.
Q:What is the concept of nonstandard channel steel compared with the national standard channel steel? Is there any difference in size between the national standard channel steel and the material?
Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-40#. Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, and channel steel is often used in conjunction with i-beam.
Q:The parameters of the channel steel of Q235B
The execution standard is GBT706-2008 angle groove
Q:Channel 18, number 18. What does it mean?
The theoretical weight of 19.752 kg per metre, channel 18#a specifications 180X, 68x 7 mm, theoretical weight of 20.174 kg per meter, channel 18#b specifications 180 X70 x9mm, theoretical weight of 23 kg per meter, specifications are x height, X leg width, waist thickness.
Q:Duplex building intermediate layer with channel steel or cast well?
Double story building, intermediate layer with channel steel and cast in place each has advantages and disadvantages, the following detailed description:1 、 cast-in-placeAdvantages: strong, relatively sound insulationDisadvantages: self importantMethods: in the load-bearing wall planting steel, tied with steel, formwork, pouring 10~12cm, waiting for about 28 days molding (summer time is slightly shorter)
Q:After the type of channel is not marked A or B, which shall be calculated?
Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The specification of channel steel is expressed by the height of the waist (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means that the waist height is 100 mm, the width of the leg is 48 mm, and the thickness of the channel is 5.3 mm, or 10# channel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on. In general, according to the model a, B, C order, its thickness (or intensity) increased in turn
Q:Which way is it better to weld the iron channel and galvanized steel channel in the house?
Can be, do not want to paint on the steel galvanized, of course, Ironweed endurance
