Carbon Steel H Beam for Structural Projects

Xi'an Dongmeng Group Co., Ltd. supplies carbon steel H beams for structural columns, beams, warehouses, workshops, bridges, platforms and equipment supports. Our H-shaped sections are available in hot-rolled and welded built-up configurations, with material options including Q235B, Q355B, ASTM A36, ASTM A572 Grade 50, ASTM A992, S235JR and S355JR, subject to section and project requirements.

Carbon steel H beams combine a central web with broad flanges to provide efficient load distribution, good bending resistance and improved lateral stability. Standard sections such as HW, HM, HN, HEA, HEB, HEM and North American W-shapes can be supplied according to the required dimensional standard, grade, length and quantity.

Processing services may include cut-to-length, sawing, drilling, hole making, edge preparation, shot blasting, primer coating, painting and hot-dip galvanizing. Each order can be supported with dimensional inspection, chemical and mechanical test results, EN 10204 3.1 MTC or an applicable mill test report, third-party inspection and seaworthy export packing.

A carbon steel H beam is a structural steel section consisting of one central web and two broad, parallel flanges. Compared with conventional narrow-flange I beams, H beams normally provide greater flange width and better stability, making them suitable for both vertical compression and horizontal bending loads.

H beams are widely used in:

Steel structure warehouses

Factory workshops

Commercial and industrial buildings

Bridges and access platforms

Equipment support frames

Mezzanine floors

Infrastructure and foundation projects

Solar mounting structures with suitable corrosion protection

H beam selection should be based on the structural calculation, span, axial load, bending moment, buckling condition, connection design and environmental exposure.

The exact dimensions, mass per meter and tolerance must be confirmed against the applicable standard section table.

By Manufacturing Method

Hot-Rolled H Beam

Hot-rolled H beams are formed through an integrated rolling process. They offer consistent mechanical properties, stable dimensions and efficient production for standard structural sections.

Welded Built-Up H Beam

Welded H beams are fabricated by assembling and welding steel plates. They allow customization of web height, flange width, web thickness, flange thickness and overall length.

Tapered or Special H Beam

Tapered and special welded H beams can be designed for large-span structures, special loading conditions and project-specific architectural or engineering requirements.

Q355B, ASTM A572 Grade 50 and S355 are high-strength structural steel grades rather than plain low-carbon steel in a strict metallurgical sense. However, they are commonly included in international carbon steel structural product categories.

For ASTM projects, H beams are usually specified as structural shapes according to ASTM A6, with the material grade defined by ASTM A36, A572 or A992. For European projects, section dimensions may follow EN 10365 while the material grade follows EN 10025.

H beam dimensions normally include:

Overall section height, h

Flange width, b

Web thickness, tw

Flange thickness, tf

Overall length, L

Example:

H 300 × 300 × 10 × 15 × 12,000 mm

This normally indicates:

Section height: 300 mm

Flange width: 300 mm

Web thickness: 10 mm

Flange thickness: 15 mm

Length: 12,000 mm

For North American sections, a designation such as W12 × 26 refers to a wide-flange shape with a nominal depth of approximately 12 inches and a nominal mass of 26 lb/ft. The final section dimensions must be verified according to the applicable ASTM section table.

The following dimensions represent common hot-rolled carbon steel H beam sections. Actual availability depends on the selected standard, steel grade, production mill and order quantity.

General Specification Range

HW Wide Flange H Beam Sizes

 HW sections are commonly used for columns, structural frames, heavy supports and industrial buildings.

HM Medium Flange H Beam Sizes

HM sections are suitable for heavy-duty columns, beams, factory buildings, platforms and equipment supports.

HN Narrow Flange H Beam Sizes

 HN sections are commonly selected for structural beams, bridge beams, long-span structures and load-bearing frames.

European and North American H Beam Sections

Length and Processing Options

Theoretical mass is normally taken from the applicable standard section table.

For preliminary calculation:

Theoretical Mass (kg/m) = Cross-Sectional Area (cm²) × 0.785

The final mass may vary because of fillet radius, rolling tolerance, cutting and processing. For quotation and shipment, the final mass should be confirmed according to the selected standard and purchase order.

Mill Finish

Black or mill-finish H beams are suitable for indoor structures or projects requiring subsequent painting, blasting or coating.

Shot-Blasted and Primed

The surface is prepared by abrasive blasting and then protected with a shop primer. This option is often used before final coating at the construction site.

Painted or Epoxy-Coated

Paint and epoxy systems can be selected for industrial buildings, platforms and environments with increased corrosion exposure.

Hot-Dip Galvanized

Hot-dip galvanizing provides a zinc coating for outdoor and humid environments. The required coating standard, coating thickness, bath size and handling method should be confirmed before production.

For large H sections, galvanizing feasibility should be checked according to the galvanizing bath dimensions, lifting capacity and potential distortion control requirements.

For North American projects, W-shapes are often commercially called wide flange beams. The exact section designation should be confirmed according to the project drawings and ASTM section

According to drawings and purchase-order requirements, the following processing services can be arranged:

Cut-to-length

Saw cutting

Drilling and hole making

Slotting

Edge preparation

Notching and coping

Plate welding and stiffener assembly
