A warehouse in a snow region, a hangar on a coast and a workshop inland do not share one wind speed. The map below is a way to organise questions, not a claim that a permit exists in each region.
Tabs group the checks we ask suppliers to address before a portal-frame package is quoted. Standards named by buyers become project-specific requests for the supplier and engineer of record to verify, never a badge on this sourcing service.
North American buyers may ask suppliers to price against ASCE 7 wind and snow inputs and the local IBC occupancy classification. Our comparison records the stated wind speed, exposure, ground snow load and seismic basis so supplier offers use the same assumptions. The selected supplier must provide calculation evidence and the engineer of record must assess local approval. Coastal hangars add door wind-lock details and corrosion at the apron; inland warehouses may call for a different coating schedule.
Hangar geometry is local even inside one country. Aircraft hangar size in metres comes from the wingspan, the tail, the tow path and the door. Publishing one hangar size chart would hide those inputs. Maintenance bays also need jacking height under the wing, which can raise the clear height without changing the door head.
European buyers may request EN 1993 action combinations and EN 1090 execution evidence from a shortlisted supplier. Our desk asks for the specified execution class, current certificate scope where applicable, and traceable material records. We do not promise a supplier will qualify or a local approval will pass. Middle East coastal and desert projects raise different corrosion questions: salt humidity and windblown abrasion should not be treated as one exposure.
Cold storage enquiries in this region often ask for a U-value. The worksheet separates core conductivity from the thermal bridge at steel columns and from the dock door. EN 14509 can describe a self-supporting panel. It does not, by itself, rate the column joint or the personnel door.
Buyers across Africa, Southeast Asia and the Pacific may adopt a national wind map, ASCE 7 or a Eurocode annex through their local engineer. Our desk leaves the code cell open until that choice is written. Shipping comparisons then separate knock-down bolted frames from long welded rafters. The selected supplier must confirm piece lengths, container count, lift weight and destination-port constraints.
Workforce support buildings beside a warehouse, such as a site office, are a different occupancy from the storage hall. Fire and sanitary rules follow the use. The selected supplier should not label a storage frame as a dormitory package without a separate plan.
Tell the desk the country, the occupancy and whether a crane, a cold room or an aircraft door is part of the hall. Those three facts change purlin spacing, column depth and the coat system more than a color swatch does.
