Engineering Recommendation: For steel structures designated for outdoor, high-humidity, coastal, or highly corrosive environments, we strongly advise evaluating corrosion classes and coating systems during the initial design phase to prevent escalating long-term maintenance costs.
What documentation is required to begin a structural steel project?
We recommend providing architectural drawings, structural blueprints, reference imagery, estimated dimensions, the project location, site photos, material specifications, preferred surface treatments, and the anticipated timeline. If complete drawings are not yet available, F.I.T. can assist in evaluating manufacturing feasibility based on your preliminary project requirements.
Can F.I.T. assist with 3D modeling and shop drawing detailing?
Yes. F.I.T. utilizes advanced 3D software for structural steel modeling, component breakdown, connection analysis, and shop drawing detailing. We seamlessly translate design concepts into precise fabrication drawings optimized for cutting, welding, transportation, and on-site erection.
Why is Total Station surveying and layout necessary?
Total Station technology significantly increases the precision of on-site dimensional sampling, benchmark verification, and layout staking while eliminating manual measurement errors. It provides an exceptionally accurate data foundation for aligning structural steel installation points, anchor bolt locations, grid lines, and large-scale component placement.
What is 100% in-factory pre-assembly?
100% in-factory pre-assembly involves trial-fitting fabricated components in our shop according to their actual erection sequence before shipping. This process verifies dimensions, hole alignments, angles, curvatures, and joint connections, effectively eliminating field errors and reducing costly on-site modification time.
Can F.I.T. fabricate custom geometric steel structures or curved components?
Yes. F.I.T. evaluates and engineers custom fabrication methods for curved steel structures, architectural spiral staircases, geometric canopies, landscape installations, and specialized steel configurations. Feasibility and production methods are assessed based on material specifications, dimensions, thickness, bending radii, and on-site installation constraints.
What surface treatment options are available for structural steel?
Common surface treatments include commercial blasting/grinding, anti-corrosive primers, topcoats/liquid paint, powder coating, hot-dip galvanizing (HDG), and specialized coating systems. For structures designated for outdoor, high-humidity, or high-corrosion environments, we recommend determining the appropriate corrosion class and coating system during the early planning stages.
