How Gelan Reduces Risk in Industrial Steel Structure Projects
Gelan helps EPC contractors, engineering companies, and plant owners reduce common risks in custom industrial steel structure projects.
From fit-up accuracy and weld quality to documents, coating, and export delivery, we check key points before fabrication to support smoother installation, review, and handover.
Reduce Site Fit-Up Rework
If the steel structure does not match base plates, anchor points, duct openings, stack connections, or platform interfaces, site teams may need cutting, drilling, or rework during installation.
How Gelan helps:
- Review layout, interfaces, and site limits before fabrication
- Check base plates, mounting holes, duct / stack interfaces, and platform connections
- Reduce site modification and installation delay
Support Weld Quality and Acceptance Review
Welding quality directly affects structure strength, inspection approval, and long-term project safety. Missing weld records or poor weld control can slow acceptance.
How Gelan helps:
- AWS D1.1 welding support for project-required steel structures
- AWS CWI qualified technical staff for welding quality review
- Support weld inspection, dimensional check, coating inspection, and NDT when required
Match Steel and Coating to Real Service Conditions
Industrial steel structures may work outdoors, near high-temperature equipment, flue gas ducts, humid areas, or corrosive plant environments. Wrong material or weak coating can shorten service life.
How Gelan helps:
- Support project-specified steel grades
- Match blasting, primer, painting, galvanizing, or anti-corrosion coating to project needs
- Improve durability in real plant environments
Prepare Documents for EPC and Owner Review
A finished steel structure is not enough if project documents are missing. EPC teams and owners often need records before shipment, installation, and handover.
How Gelan helps:
- Provide material certificates, welding records, inspection records, and coating records
- Prepare packing lists and handover files with the steel structure package
- Reduce approval delays caused by incomplete documents
Support Newbuild, Export, and Revamp Delivery
New projects need clear packing, marking, and delivery planning. Revamp projects often need replacement steel parts that match old equipment, limited space, and existing interfaces.
How Gelan helps:
- 500 tons/month export capacity for industrial steel structure packages
- Support loose parts, pre-assembled sections, modular frames, and replacement steel structures
- Fit new projects, plant repair, retrofit work, and equipment upgrades
Where Gelan Steel Structures Are Used
Gelan steel structures are used in industrial projects where equipment support, access, duct routing, modular frames, and replacement parts must match real site conditions. We support steel structure packages for oil, petrochemical, refining, chemical, energy, and emission control projects.
Heavy Steel Structure Fabrication Project Support By Gelan
Equipment Support Steel Structure for a Refinery Project
Project Background:
A custom steel support structure was required for refinery equipment, with load, access, wind, seismic, and installation conditions reviewed before fabrication.
Gelan Support:
- Reviewed equipment layout, support points, and load combinations
- Checked strength, vertical deflection, wind drift, and seismic drift
- Prepared calculation and handover documents for project review
Result:
- Strength utilization ratio < 1
- Vertical deflection checked by L/300
- Wind drift checked by H/200
- Seismic drift checked by H/200
- Easier project review, safer installation, and smoother handover
FAQ About Industrial Steel Structures
1. What is structural steel fabrication for industrial equipment?
Structural steel fabrication means cutting, welding, assembling, inspecting, and delivering steel structures for process equipment.
For Gelan, this can include furnace support structures, equipment support frames, modular skid frames, platforms, ladders, duct supports, casing supports, and replacement steel structures.
