Pre-engineered steel buildings
Ask each supplier to state the primary steel grade, connection type and drawing deliverables. Treat Q355 and S355 as separate specifications until the engineer reviews proposed substitution.
Open the span table
Compare portal-frame proposals on one set of inputs. Dean Steel Buildings coordinates supplier screening, quotation comparison and inspection requests for pre-engineered steel buildings sourced from China.
A clear span belongs beside the eave height, bay spacing and site load basis. Ask the project engineer to confirm those inputs before issuing the same brief to suppliers.
Start with the frame package or a use-specific steel shell. Add purlins, girts and cladding as separate bid lines so a bare-frame offer stays comparable with a weather-tight package.

Quote the logistics shell with its clear height at rack aisles and dock doors. For workshops, record the crane runway scope separately from the columns and rafters.

Supply the aircraft envelope, door operating loads and target clear opening to screen a hangar proposal. Those inputs affect the header and bracing even when building width stays fixed.
Browse hangar framesThe scenarios below are illustrative RFQ briefs. They show how to record a comparison scope without implying completed work, named customers or supplier performance.
Leave room for both racking and dock interfaces when you set the eave height. Ask the supplier to show clearances at the haunch.
Share the door track section with bidders so support steel and door supply can be priced independently.
If a crane is planned, give suppliers wheel loads and hook height. Flag missing crane data for follow-up.
Write the occupancy and acoustic lining scope into the brief for a teaching hall. Keep local review separate from the frame package.
Send the existing grid and roof levels when the new bay adjoins a building. Confirm who owns the interface survey.
Ask for coating preparation, dry-film thickness and repair instructions when the site faces salt or chemical exposure.

Provide the project location, clear span and delivery port. We can coordinate the same quotation basis across shortlisted suppliers and record which documents each bid includes.
