Hot Rolled & Welded H-Beam | Structural Steel for Heavy Loads, Custom Cutting, Welding & Coating
1. Product Overview
Our H-beam is a high-performance structural steel component manufactured in strict accordance with GB/T 11263 national standards. Conventional grades include Q235B and Q355B, with high-strength Q420 and Q460 grades available for custom production. The product covers two main categories: hot rolled H-beam and welded H-beam. Featuring symmetrical H-shaped cross-section, high section modulus, excellent bending rigidity and uniform stress distribution, H-beams serve as core load-bearing components in steel structure engineering. They are widely applied for steel columns, steel beams and main frame structures in industrial workshops, warehouses, high-rise buildings, stadiums, bridges and municipal projects. We also support one-stop deep processing services such as precision cutting, welding, drilling, derusting and anti-corrosion painting to deliver finished components ready for installation. All processing work is undertaken by our professional Steel Structure Material Processing team.
2. Product Classification & Specifications
Product Types
Hot Rolled H-Beam: Produced complying with GB/T 11263 standard, covering complete HW (wide flange), HM (medium flange) and HN (narrow flange) series. It features standard dimensional accuracy, flat surface and no welding residual stress, with sufficient in-stock supply for fast delivery.
Welded H-Beam: Fabricated through steel plate assembly and automatic welding. It supports customized variable cross-section, arc shape, unequal thickness, height and width designs, meeting special structural and architectural requirements that standard hot-rolled sections cannot satisfy.
Technical Parameters
Section Height: 100mm–900mm (welded type maximum up to 1200mm, subject to steel plate thickness and production capacity) Flange Width: 50mm–400mm Plate Thickness: 6mm–32mm Standard Length: 6m, 9m, 12m; arbitrary cutting and non-standard custom sizes are acceptable
3. One-stop Deep Processing Service
As a professional steel structure processing manufacturer, we provide drawing optimization and full factory prefabrication services, delivering fully finished structural parts for direct on-site assembly. The complete processing workflow covers drawing deepening, CNC precision cutting, punching and drilling, edge beveling, automatic assembly, SAW/CO₂ precision welding, mechanical straightening, shot blasting derusting, anti-corrosion coating, final inspection and unified packaging.
We customize various finished products, including standard steel beams and columns, large-span portal rigid frames, equipment support frames, mezzanine main beams and all types of load-bearing frame components for industrial and construction projects.
4. Core Product Advantages
High Structural Strength & Lower Engineering Cost Under the same height and weight specifications, H-beams deliver 30% to 50% higher bending capacity than traditional I-beams. Compared with concrete structures, they reduce overall weight by up to 60%, effectively lowering foundation load and cutting total construction investment.
Large-span Layout & Higher Space Utilization It supports 18m to 30m column-free large-span structural design. Larger spans can be achieved with enlarged section sizes, creating spacious and open indoor space and maximizing building area utilization for industrial and public buildings.
Excellent Toughness & Reliable Seismic Performance With superior ductility and structural toughness, the H-beam adopts professional seismic structural design. It meets GB 50011 standard for 8-degree seismic fortification, effectively resisting structural cracking and collapse under external impact and vibration.
Long-lasting Anti-corrosion & Eco-friendly Structure We provide professional shot blasting and multi-layer anti-corrosion treatment in line with ISO 12944 standards. Custom C5 high anti-corrosion grade is available for offshore facilities and heavy industrial corrosive environments. The main structure achieves a 50-year design service life, with a 5-year warranty for anti-corrosion coatings. All steel materials are fully recyclable, generating minimal construction waste and conforming to green building requirements.
Powerful Customization & Wide Application Compatibility Custom services cover variable cross-sections, arc structures, special-shaped frames, thickened and widened sections, adapting to complex structural demands of industrial factories, municipal facilities and landscape engineering projects.
5. Application Scenarios
Industrial Buildings: Load-bearing beams and columns, large-span portal frames, equipment supports, structural frames for cold storage, logistics warehouses and agricultural steel buildings.
High-rise Construction: Main load-bearing frames for high-rise office buildings, commercial complexes and prefabricated steel structure buildings.
Public Venues: Long-span roof beams and truss structures for stadiums, exhibition centers, high-speed railway stations and airport buildings.
Municipal Engineering: Pedestrian overpasses, landscape steel frames, EV charging shelters, photovoltaic support brackets and urban decorative steel structures.
Special Structural Projects: Large-scale equipment bases, chemical pipe racks, steel trestles and outdoor billboard load-bearing frames.
6. Delivery, Packaging & Custom Service
Delivery & Lead Time
Stock Supply: Full range of standard hot-rolled H-beams are in stock, available for delivery within 3–5 working days. Custom Processing: Welded H-beams and deep-processed finished components take 10–18 working days after drawing confirmation. We accept DWG and PDF design drawings and provide professional drawing deepening and optimization services. MOQ Requirement: 1 ton for in-stock hot-rolled beam orders; welded custom products require a minimum length of 6m and a minimum order quantity of 5 tons.
Packaging & Export Solution
Standard steel sections are tightly bundled and fixed for protection, while large finished components are supported with skids to avoid deformation. For export shipment, products are treated with anti-rust oil or VCI protective film and packed with fumigated wooden pallets, fully adapted to long-distance sea transportation. Complete export documents are provided, including packing list and certificate of origin. All products are delivered with mill test certificates, Grade 1/2 UT welding inspection reports and anti-corrosion test reports. Supported by 5-year coating warranty and 50-year structural design lifespan, our products fully meet global project acceptance standards.
7. FAQ
Q1: How to choose between hot rolled H-beam and welded H-beam? A1: For standard conventional cross-sections, hot-rolled H-beams are preferred for higher cost performance and shorter lead time. For non-standard, variable or oversized sections, welded H-beams offer flexible customization without mold costs, ideal for small-batch and multi-spec special projects, though with higher MOQ and longer production cycle.
Q2: Can you provide shot blasting and anti-corrosion painting services? A2: Yes. We deliver Sa2.5 grade shot blasting treatment complying with ISO 8501-1 standard. Custom C3, C4 and C5 anti-corrosion coating systems are available to adapt to indoor dry, outdoor exposed, humid and heavy corrosive working environments.
Q3: Can you fabricate custom steel beams and columns according to client drawings? A3: Full drawing-based customized fabrication is supported. All structural components are completely prefabricated in the factory for direct on-site assembly, greatly reducing on-site welding workload and improving overall construction efficiency and safety.
