Structural Fabrication FAQs
Clear answers regarding design, cost, timelines, and specifications.
Can you fabricate custom mezzanine floors inside an existing shed?
Yes. We design and install self-supporting structural steel mezzanine floors inside existing buildings, engineered specifically around your floor space, load requirements (e.g. 500–1500 kg/m²), and access stairs.
What quality checks are performed on fabricated structural members?
We conduct dimensional verification, camber checks, weld throat thickness measurements, and dye-penetrant testing (DPT) on critical structural joints before dispatch.
Do you supply and install crane rails for overhead cranes?
Yes. We supply crane rails (CR-80, CR-100, etc.), forged clamping clips, resilient rubber pads, and crane stop buffers alongside the gantry girders.
