Galvanized H beam steel is a structural steel section with a central web and two horizontal flanges. The H-shaped geometry provides an efficient section for axial, bending and framing applications when the correct size is selected through structural design.

The designation normally uses four dimensions:

H - nominal section height

B - flange width

tw - web thickness

tf - flange thickness

For example, H200 × 200 × 8 × 12 identifies the nominal height, flange width, web thickness and flange thickness.

H sections may be named differently in different markets. Chinese projects may specify HW, HM or HN sections. European projects may use HEA, HEB, HEM, UB or UC sections. North American projects commonly use W-shapes or wide-flange sections.

These designations are not automatically interchangeable. Buyers should provide the governing standard, grade, complete section designation and approved beam schedule.

Hot-rolled H beams and welded built-up H beams are also different products. Custom welded sections should be quoted separately according to the drawing, welding requirements, dimensional tolerances and inspection plan.

Recommended purchasing information includes:

Galvanizing standard

Coating thickness or coating grade

Surface appearance requirements

Coating adhesion requirements

Inspection method

Drainage and venting requirements for fabricated parts

Cut-edge repair requirements

Whether drilling, welding or cutting is required before galvanizing

For structural shapes, coating requirements may depend on the steel thickness and the applicable galvanizing standard. A single coating value should not be used for every section and every project.

Whenever possible, drilling, cutting and welding should be completed before hot-dip galvanizing. If post-galvanizing processing is necessary, the affected areas should be repaired according to the agreed coating-repair procedure.

 

 

High load-bearing capacity – suitable for heavy-duty construction

Durable and long-lasting – resists bending, twisting, and corrosion (with protective coating)

Easy fabrication – hot-rolled for dimensional precision, weldable, and machinable

Versatile applications – bridges, high-rise buildings, industrial factories, warehouses

Customizable lengths & sizes – supports project-specific requirements

Galvanized H beam steel may be specified for:

Industrial building frames

Warehouse structures

Steel columns

Outdoor platforms

Equipment support frames

Agricultural structures

Solar support structures

Walkways and maintenance platforms

Infrastructure components

General structural fabrication

For bridge, marine, offshore, seismic or heavy-load applications, the required steel grade, impact performance, coating system and inspection plan must be confirmed before quotation.

Select the Section

Choose the complete section designation rather than ordering only by nominal height.

Example:

H200 × 200 × 8 × 12

The same nominal height can have different flange widths, web thicknesses, section properties and unit weights.

Select the Steel Grade

Q235B / ASTM A36 / S235JR: commonly considered for general structural applications when permitted by the project specification.

Q355B / S355JR / ASTM A572 Grade 50: considered when higher specified yield strength is required.

ASTM A992: commonly specified for North American structural shapes and wide-flange applications.

SS400: used for projects following applicable Japanese or Asian specifications.

The final grade should be selected by the structural designer or project specification. A higher-strength grade does not automatically allow a smaller section.

Select the Coating

Use hot-dip galvanized H beams when the project requires additional atmospheric corrosion protection for outdoor or exposed steelwork.

The coating decision should consider:

Rural, urban, industrial or coastal exposure

Expected maintenance conditions

Required service environment

Fabrication sequence

Repair of cut or welded areas

Compatibility with later paint systems

Check the Design

H beam selection must consider:

Span

Applied loads

Axial compression

Bending moments

Shear

Lateral stability

Local buckling

Connection design

Support and restraint conditions

Fire and seismic requirements where applicable

This product page does not replace structural calculations or an approved engineering design.

1. What information is required to quote a galvanized H beam?

Please provide the section designation, steel grade, governing standard, coating requirement, length, quantity, processing requirements and destination.

2. What does H × B × tw × tf mean?

It represents section height, flange width, web thickness and flange thickness in millimetres.

3. Are H beams and I beams interchangeable?

No. Market terminology may overlap, but section geometry, dimensions, section properties and design requirements can differ. Use the approved beam schedule instead of relying only on the product name.

4. Which standards can be supplied?

Depending on the project, supply may be arranged according to GB/T, ASTM, EN or JIS requirements. The applicable section, grade and coating standards should be specified separately.

5. Is the galvanized coating hot-dip galvanized?

The coating route should be confirmed in the quotation. For structural H sections requiring hot-dip galvanizing, the applicable coating standard and coating requirement should be stated in the purchase order.

6. Can you supply custom lengths?

Typical lengths include 6 m, 9 m and 12 m. Custom lengths may be available subject to production, transport and project requirements.

7. Can you supply custom welded H sections?

Custom welded H sections may be coordinated according to approved drawings. Welded sections are quoted separately from standard hot-rolled profiles.

8. Can galvanized H beams be cut or drilled?

Cutting and drilling may be arranged before galvanizing where possible. Post-galvanizing processing may require repair treatment for the affected coating areas.

9. Do you provide MTC and inspection documents?

MTC / EN 10204 3.1 and inspection documents may be provided according to the material, applicable standard and purchase-order requirements. Third-party inspection can be coordinated by prior agreement.
