We are a factory and supplier of large heavy duty H-beam, I-beam, U-beam, C-beam, steel sheet piles. We can supply a large number of standard size stock at any time, can also be customized according to the customer's drawings, we can meet the inspection and certification requirements.
Most I beams use structural steel fabricated by a steel fabricator, but some are made from aluminum. Infra-metal constructions, such as carbon structural steel and high-strength low-alloy structural steel, have different applications – such as building framing, bridges, and general structural purposes.
Due to the relatively high and narrow cross-section sizes, the moment of inertia of the two main sleeves are quite different, which limits the application of the common i-beam and light i-beam. The use of i-beams shall be selected according to the requirements of the design drawings.

(1) Composition Index: The chemical composition of angle steel belongs to the rolling steel series for general structure, the main verification index is C, MN, P, s four items. According to the different grades, The content varied from C & Lt; 0.22% , Mn: 0.30-0.65% , P & lt; 0.060% , S & lt; 0.060% .
(2) inspection methods: The commonly used standard inspection methods are GB223, JISG1211-1215, BS1837, BS manual 19,22536, etc.
Processing Technology Of Q355B Steel I- beam
The flange of ordinary i-beams and light i-beams is gradually thinned from the root to the edge at a certain angle. The models of ordinary i-beams and light i-beams are represented by the Arabic numerals of the number of centimeters in their waists, web, flange thickness and flange width of different specifications to waist height (h) × leg width (b) × waist thickness (d) of the number of millimeters, such as “General work 160 × 88 × 6”, that means waist height of 160 mm, leg width of 88 mm, waist thickness of 6 mm common i-beam. /“Light Industry 160 × 81 × 5”means light i-beam with a waist height of 160 mm, a leg width of 81 mm and a waist thickness of 5 mm. The specification of common i-steel can also be expressed by model number, which indicates the number of centimeters of waist height, such as common i-steel 16 # . If there are several different leg widths and waist thicknesses, a B C should be added to the right side of the model, such as 32 # A, 32 # b, 32 # C, etc. . Standard Specification for hot-rolled plain i-beams is 10-63 # . The size of hot-rolled common i-beam supplied by agreement of both the supplier and the demander is 12-55 # .
