Brief Description

Hot-dip galvanized I-beam with all bracket cleats, gusset plates, and top flange tabs shop-welded before galvanizing - zero site welding required. Designed for mezzanine floors, equipment platforms, catwalks, and access walkway support systems.

Detailed Description

This galvanized I-beam with pre-welded bracket cleats and gusset attachments is purpose-built for mezzanine and platform support systems where secondary beams, decking, handrails, and equipment mounts must connect to the primary beam without site welding. All attachment points - rectangular top flange tabs (2 holes each), triangular web gusset plates between bottom flange and web, and complex multi-plate end brackets - are shop-welded to the beam using custom jigs and laser alignment, then the complete assembly undergoes hot-dip galvanizing in a single immersion. This weld-first-then-galvanize sequence ensures that every weld bead, every bracket edge, every gusset corner, and every bolt hole receives full metallurgical zinc protection - coverage that paint alone cannot achieve, especially in crevices and under-bracket areas. Top flange tabs and end brackets are positioned with laser-guided jigs, guaranteeing that mating columns, secondary beams, and edge angles connect without forcing or field modification. For quality assurance, we pre-assemble each beam with a sample of its mating components in the shop before shipment, verifying all bolt hole alignment. Beams are fabricated from Q235B or Q355B hot-rolled I-sections, with welded built-up sections available for non-standard depths. Standard beam length is 1m to 12m per piece, with HDG coating to ISO 1461 (70-100μm). Each beam ships as part of a complete kit: matched bolts, connector plates, and an exploded-view assembly drawing. For full mezzanine projects, we also supply columns with base plates, secondary infill beams, edge angles for decking support, handrail/guardrail systems, and floor decking (steel grating, checkered plate, or composite deck) - all connections pre-engineered for full compatibility.

Product Attributes

Product Selling Points

All connections pre-welded: Every bracket, tab, gusset, and cleat is shop-welded before galvanizing - zero site welding means faster erection, no fire risk on site, and no coating touch-up

Galvanized inside and out: Because welding is done before HDG, the zinc coating covers every surface - under brackets, inside gusset corners, through bolt holes - areas paint can never reach

Precision alignment guaranteed: Top flange tabs and end brackets are positioned using a jig and laser alignment system, ensuring mating components connect without forcing or field modification

Reduced site labor: A typical mezzanine beam with shop-welded brackets can be installed by a 2-person crew in 15 minutes per beam, vs 45+ minutes for a beam requiring multiple bolted/hole-drilled site connections

Safety advantage: Shop fabrication under controlled conditions eliminates fall-from-height welding, grinding, and hot work permits on site - a significant EHS benefit for occupied building retrofits

Company Advantages

Custom bracket design service: Send us your layout; we engineer every bracket, cleat, and gusset for the exact connection geometry and load - no generic off-the-shelf brackets

Galvanizing after fabrication: All brackets are welded first, then the complete assembly is HDG galvanized - every weld, every bracket edge gets full corrosion protection

Assembly-fit verified: We pre-assemble the beam with a sample of mating components (columns, secondary beams) in the shop to verify all bolt holes align before shipment

Mezzanine specialist: Dedicated mezzanine & platform production line means faster turnaround (10-12 days typical) and more competitive pricing than general fabricators

Complete kit delivery: Each beam ships with its matched bolts, connector plates, and an exploded-view assembly drawing - your site team can install without confusion or missing parts

Frequently Asked Questions (FAQ)

Q1: Can you design the bracket and gusset layout from my architectural/structural drawings?

A: Absolutely. Provide your mezzanine layout (plan + sections) with column grids and load requirements. Our engineers will design all beam-to-column, beam-to-beam, and bracing connection details. We deliver a full connection design package (Tekla model + 2D shop drawings) for your approval before fabrication.

Q2: What is the advantage of shop-welded brackets vs bolted site connections?

A: Three main advantages: (1) Speed - no site drilling/bolting for secondary connections, cutting installation time by 60%+. (2) Quality - shop welding under controlled conditions with NDT inspection. (3) Corrosion - the entire assembly, including welds, gets galvanized protection. Bolted site connections require touch-up painting that never matches the original galvanized finish.

Q3: How do you prevent the beam from twisting or distorting during galvanizing?

A: We design bracing tabs and lifting points to act as anti-distortion restraints during HDG immersion. For long slender beams, we may add temporary bracing that is removed after galvanizing at the touch-up points (which are small and easily coated with zinc-rich paint). Our 12-year track record in galvanized bracket fabrication means we know exactly how each section behaves in the bath.

Q4: Can you also supply the connecting columns, handrail posts, and decking?

A: Yes, we offer a complete mezzanine package: primary beams (your main order), secondary infill beams, columns with base plates, edge angles for decking support, handrail/guardrail systems, and floor decking (steel grating, checkered plate, or composite deck). A single-source package simplifies procurement and ensures all connections are compatible.
