Specialized Steel Structures

For towers, the most effective savings come from selecting the right bracing pattern, leg slope and section shape, which together control wind area and tonnage. On platforms and access structures, we standardize stair, ladder and handrail modules and use galvanized bolted assemblies that eliminate site welding. Designing equipment supports with the supplier interface fixed early avoids redesign later, protecting both fabrication schedule and installation dates.

Members include angle and tubular tower legs and bracing, built-up platform beams, grating and checker plate decks, stair stringers, ladders with cages and heavy equipment base frames. Tower sections are fabricated with precise bolt hole patterns so that splices assemble without reaming. Where fit-up is critical, tower panels or equipment frames can be trial assembled in the shop. Every piece is marked with section, face and elevation references matching the erection drawings.

We prepare an inspection and test plan tailored to the structure type, including traceability of all members through mill certificates and heat numbers. NDT is selected according to joint type and fatigue sensitivity, such as magnetic particle testing on base plate welds and ultrasonic testing on full-penetration joints. Dimensional checks confirm hole patterns, verticality references and interface geometry. All results are compiled in a QC dossier per the execution or welding standard specified.

Towers and outdoor platforms are frequently exposed to C4, C5 or CX conditions in coastal, offshore-adjacent or industrial settings. Hot-dip galvanizing to ISO 1461 or AS/NZS 4680 is our preferred protection for bolted towers and access steel, with duplex systems combining galvanizing and ISO 12944 paint where longer maintenance intervals or color marking are needed. Fasteners are specified with matching corrosion protection.

Bolted towers and modular access structures are well suited to containerized shipping, with members bundled by tower section or platform module and fasteners packed in labeled kits. Larger equipment frames and pre-assembled platforms travel as break-bulk with transport bracing. We sequence shipments by erection zone and issue packing lists, bolt kit registers and export documentation with every consignment.

We supply erection drawings showing assembly order, bolt tightening requirements and temporary guying or bracing where needed. Our team provides input to method statements for tower stacking, gin-pole or crane lifts, and platform installation around existing equipment. When agreed, our engineers offer technical supervision or advisory visits for critical stages, while the appointed erection contractor performs all site work.
