FAQ:

Q1: How soon can we receive the product after purchase?

A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

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.

Q:What is the ultimate capacity of steel structures?
I. The ultimate bearing capacity of steel structure means failure due to fatigue.Two 、 the ultimate limit of bearing capacity is the state that has been destroyed and can not be used. The serviceability limit state is also barely usedThree, the structure or component to the maximum carrying capacity, or reach the limit state of deformation which is not suitable for continued load.
Q:Measures to prevent rust in welded seam of steel structure
Steel structure welding rust treatment measures: usually first paint Antirust Primer, and then coated with surface paint can.The choice of antirust primer and finish coat shall be determined according to the actual use situation.
Q:How is the steel structure foundation checked and accepted?
The column position in the column surface measuring axis of projectile.Level of plinth elevation. Concrete plinth elevation 50 ~ 60 mm for general casting (compared with steel column base design, installation in elevation) with steel plate or early adoption by plasma plate leveling.When using the steel plate support plate, steel plate area should be determined according to the fastening force and compressive strength, concrete of foundation base plate two times before grouting at the bottom of the column load and anchor bolt. The contact between the shim and the base and the bottom of the column should be smooth and tight.When the cushion plate is used, the shrinkage free mortar shall be adopted. The strength of the mortar block should be higher than that of the base concrete before the lifting of the column, and the mortar pad should have enough area to meet the requirements of the load.
Q:How to consider the influence of base displacement on steel structure
The vertical deviation is too large and the height of the column column below the design elevation. The high-rise steel structure engineering, steel structure engineering of column soleplate gap is too large or difficult iron pad placed in the assembly process will. It is also found that the spacing between columns is too large or too small, and it is often found that the top elevation at both ends of the beam is inconsistent.
Q:What does the steel structure lug 2-240*290*12 mean?
There are no bridge steel structure, the building itself is not such, clever special connections to solve the problem of building cold bridges by using the technique of the cable truss structure; small and water pipes through the wall, construction decoration is convenient.
Q:What is called steel structure?
Building structure type:Steel structure is mainly made of steel material, and it is one of the main types of building structure.The structure is made up of steel beams, steel columns and steel trusses made of shape steel and steel plate.Joints, bolts, or rivets are usually used between components or components.Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:What is the difference between steel structure, light steel workshop, color steel room and movable room?
The main difference between the company's light steel structure and the color steel plate movable room is that the materials used by the two are different, and the prices are different. Choi steel movable room is relatively simple, safe and practical. Light steel structure seismic, light weight, environmental protection, construction cycle fast.
Q:The position of the steel structure requires a spring cushion for mounting the bolt
High strength bolts (friction type) should be pre tension, and the spring washer is unfavorable to exert the pretension; the friction force produced by the high strength bolt in the preload moment is enough to prevent the looseness; therefore, no additional measures are needed to prevent loosening. Therefore, high strength bolts should not be equipped with spring washers.
Q:What is called a steel rivet?
It's going to be an antique. Aluminum or steel rivets are used for locking structures when they are used for retaining structures, not for structural purposes. As for the thin steel plate, the steel structure is not good, and at the very least, the structural professional pays little attention to rivet pulling.
Q:What does steel structure cross section L75*5 mean?
The "L" in the drawing of the steel structure refers to the angle steel, the 75 is the angle steel limb width, and the 5 is the angle steel thickness, so the steel structural section L75*5 represents the equilateral steel angle with 75mm 5mm and wall thickness of both sides.
