What is I Beam?

An I beam is a structural steel profile with an I-shaped cross-section, featuring parallel flanges connected by a central web. This geometry provides exceptional load-bearing capacity with minimal material weight, making it the preferred choice for columns, girders, and framework in commercial and industrial construction.

I Beam Technical Specifications

Our I beams are manufactured from carbon steel grades including ASTM A36 (yield strength 250 MPa), A572 Grade 50 (yield strength 345 MPa), and A992 (yield strength 345-450 MPa). Standard depths range from 3 inches to 44 inches with flange widths from 2.5 inches to 16 inches, available in lengths up to 80 feet per customer requirements.

Frequently Asked Questions

What is the MOQ?

Our minimum order quantity is 10 metric tons per specification. For mixed container orders combining multiple beam sizes, we accept 5 tons minimum per profile.

I Beam Manufacturer China

Do you provide material test certificates?

Yes, we supply EN 10204 3.1 mill test certificates with every shipment, documenting chemical composition, mechanical properties, and heat number traceability. Third-party inspection by SGS or Bureau Veritas is available upon request.

What is the typical delivery time?

Standard stock sizes ship within 7-10 business days. Custom rolled profiles require 25-35 days from order confirmation, depending on tonnage and specification complexity.

Issue resolved professionally
Ordered 15 tons of W14x30 beams cut to specific lengths for a retail development. Initial shipment had 3 beams cut 15mm short of specification. Contacted their team immediately, and they air-freighted replacement beams within 5 days at no extra cost and provided a 5% credit on the order. The replacement beams were perfect. Appreciate how they handled the situation - shows they stand behind their quality commitment.

Outstanding support for repeat orders
This is our fourth order with SteelPro - 28 tons of W21x62 beams for a bridge retrofit project. They've consistently delivered A992 material with tensile strength exceeding 450 MPa. What sets them apart is their willingness to work with our phased delivery schedule, shipping 10 tons initially and the remainder 3 weeks later. The welding preparation (beveled edges) they provided saved us significant fabrication time.

Competitive pricing for standard sizes
We regularly stock SteelPro's I-beams for resale. Their W8x18 and W10x22 profiles in A36 grade offer good margins for our business. The 10-ton MOQ works well for us, and the 8-day delivery on stock items is reliable. Material certificates are always included. Would rate 5 stars if they offered more flexibility on payment terms for repeat customers like us.

Perfect for our high-rise project
Ordered 67 tons of wide flange beams (W27x94 and W33x118) for a 22-story tower in Dubai. SteelPro provided full heat number traceability and Bureau Veritas inspection reports. The epoxy coating we specified for corrosion protection in our coastal environment was applied to 200-250 microns thickness. Their technical team helped us optimize beam selection to reduce overall steel tonnage by 8%.

Good value but lead time slightly longer
Purchased 18 tons of W16x40 beams in A572 Grade 50 for a mining support structure. Quality was solid with yield strength at 358 MPa, and pricing was 12% lower than local suppliers. The custom drilling pattern we needed was executed accurately. Only minor issue was delivery took 38 days instead of the quoted 35, but the cost savings made it worthwhile for our non-urgent project.

High-quality EN 10025 compliant beams
Sourced 32 tons of IPE 300 beams in S355J2 grade for an industrial facility expansion. The material certificates showed carbon content of 0.18% and excellent impact toughness at -20°C. Custom cutting to 6.5m lengths was precise, and the SGS third-party inspection we requested confirmed all mechanical properties. Delivery from China to Hamburg took 31 days as promised.

Reliable supplier with fast turnaround
We've purchased over 120 tons of various I-beam profiles from SteelPro in the past year. Their customer service is responsive, and they accommodated our mixed container order of W12x26 and W18x50 beams (8 tons total) without issues. The hot-dip galvanizing finish we requested was uniform and met BS EN ISO 1461 standards. Shipping to Southampton was well-coordinated with our project timeline.

Excellent A992 beams for our warehouse project
Ordered 45 tons of W24x84 beams in ASTM A992 for our distribution center in Texas. The dimensional tolerances were spot-on (±2mm), and all EN 10204 3.1 certificates matched our specs perfectly. Delivery took 9 days to our site, which kept us on schedule. The yield strength tested at 352 MPa, well within the 345-450 MPa range. Will definitely use SteelPro for our next commercial build.

FAQ

Q: Q: What are the common specifications of your I-beams?

A: A: Our standard I-beams cover a wide range of section heights, from 100mm to 630mm. The common models include GB 10# to 63#, EN IPE 80 to IPE 600, ASTM W4 to W24, and JIS H 100 to H 600. The flange width and web thickness vary according to different models, and we can provide detailed dimension tables upon request.

Q: Q: What materials are your I-beams made of, and what are their mechanical properties?

A: A: We mainly produce I-beams with high-quality carbon steel and low-alloy steel. The common materials are GB Q235B/Q355B, EN S235JR/S275JR/S355JR, ASTM A36/A572 Grade 50, and JIS SS400. All materials meet the corresponding standard requirements, with tensile strength ranging from 375MPa to 550MPa and yield strength from 235MPa to 355MPa, suitable for various load-bearing structures.

Q: Q: Do you supply both hot-rolled and cold-rolled I-beams?

A: A: We mainly supply hot-rolled I-beams, which are widely used in construction, bridge, and machinery manufacturing due to their high strength, good toughness, and stable performance. Cold-rolled I-beams are available for small-size models (section height ≤ 160mm) by customization, and they are suitable for light-load structures and precision equipment.

Q: Q: Can you produce I-beams with non-standard dimensions?

A: A: Yes, we can customize I-beams with non-standard section heights, flange widths, web thicknesses, and lengths according to your specific drawings or requirements. Customized products require a higher minimum order quantity (MOQ) and a longer production cycle, and we will provide a detailed quotation based on your customization plan.

Q: Q: What is the difference between your standard I-beams and high-strength I-beams?

A: A: The main difference lies in the material and mechanical properties. Standard I-beams are made of ordinary carbon steel (such as Q235B, A36) with moderate strength, suitable for general load-bearing scenarios. High-strength I-beams are made of low-alloy steel (such as Q355B, A572 Grade 50), which have higher yield strength and tensile strength, lighter weight under the same load, and are more suitable for large-span and heavy-load projects.

Q: Q: How do you ensure the dimensional accuracy of your I-beams?

A: A: We adopt advanced hot-rolling production lines and strict quality control procedures. During production, we use professional testing equipment to inspect the section size, straightness, and flatness of each batch of I-beams. All products meet the dimensional tolerance requirements of the corresponding standards (GB/EN/ASTM/JIS), and we can provide dimensional inspection reports if needed.
