Why Choose Steelgram For Your Building Project?
- Our buildings go up fast and stay accurate. We manage the full process in-house at Steelgram – design, UKCA-certified fabrication, and installation – so you avoid common delays and misalignments from multi-contractor setups.
- Our precision engineering cuts lifetime costs. We deliver Tekla/AutoCAD-engineered frames with exact tolerances, reducing repairs, rework, and on-site issues that come with generic kit suppliers.
- Our turnaround times keep projects moving. We quote quickly, fabricate in Sheffield, and install nationwide using our own trained, insured teams, giving you reliable scheduling instead of uncertain lead times.
- Our compliance protects your project. We work under Constructionline Gold, CHAS Premium Plus, Acclaim SSIP, and full insurances – preventing the inspection failures and rework seen with unaccredited fabricators.
Our Process for Delivering Steel Buildings
1. Site Assessment & Requirements Review
We visit your site, measure accurately, and confirm access needs. This prevents design errors, redesigns, and misaligned foundations. Typical turnaround: 2-5 days for standard sites, slightly longer for complex access or existing-building tie-ins.
2. Engineering & Structural Design
We create full UKCA-compliant drawings and calculations. This removes planning/inspection risks and ensures load-fit suitability. Design phase: 1-2 weeks for standard frames, 2-4 weeks where enhanced engineering or client revisions are required.
3. In-House Fabrication
We fabricate in our Sheffield facility with strict quality control. This avoids missing parts, poor fit, and unreliable subcontracted steelwork. Fabrication: 2-4 weeks once drawings are approved, subject to tonnage and current workshop schedule.
4. Delivery, Installation & Handover
We install using our own trained, insured crews. This ensures accuracy, safe erection, and no onsite guesswork. Install time: from 2-5 days for small buildings, 1-2 weeks for mid-sized structures, and 2-4+ weeks for larger or cladded units depending on site conditions.

FAQs About Hiring Us
How fast can Steelgram deliver?
We quote quickly, design most standard buildings in 1-2 weeks, fabricate in 2-4 weeks once drawings are approved, and install shortly after. Larger or more complex builds follow a 2-4 week design phase and a 4-8 week fabrication window depending on tonnage and schedule. Best for time-critical sites. Solves deadline pressure with predictable scheduling based on real workshop capacity.
Do we handle planning and engineering?
Yes – full structural drawings, calcs, and compliance packs. Best for avoiding planning delays. Solves documentation gaps that stall projects.
Can we customise layouts and openings?
Yes – spans, eaves, doors, mezzanines, access steelwork, and cladding. Best for sites with machinery or vehicle constraints. Solves kit building limitations.
What guarantees do we offer?
UKCA-certified steel, full insurance cover, and long-life structural durability. Best for long-term operational use. Solves risk of premature wear or non-compliance.
