Steel Portal Frame Buildings | Clear-Span Hangars Up to 90m

Our steel hangar buildings deliver maximum space, structural strength, and operational reliability for airports, private flight centers, and industrial equipment depots. Engineered using high-tensile structural steel framing, these pre-engineered hangars offer custom clear-span layouts from 30 to 90 meters, accommodating large aircraft wingspans, helicopter fleets, and heavy equipment. We design customized door systems—including multi-leaf sliding doors, hydraulic bi-fold doors, and fabric roll-up doors—that integrate seamlessly into the main portal frame skeleton. Fabricated in ISO-certified facilities with automated CNC cutting and welding, our hangar structures ensure exact alignment and fast on-site bolt assembly. Paired with fire-retardant cladding, natural skylight grids, and thermal insulation, our steel hangar buildings deliver superior asset protection and long-term economic efficiency.
