Rohner for Structural Steel
Structural steel finishing can involve beams, columns, plate assemblies, bracing and welded frames moving between fabrication, blast, coating and staging. Rohner equipment for this type of work can include large equipment paint booths, blast rooms, paint mixing rooms, make-up air and exhaust systems. Double D Mechanical installs, relocates and services the booth, blast, air and utility connections that support steel finishing operations.

Steel Lengths And Bay Movement
Beams and columns need space for loading, turning, staging and removal, not just the booth footprint. The layout should consider crane reach, forklift aisles, sawhorse or cart height and the longest member expected to pass through blast and coating.
Clean Transfer After Blasting
The path from blast to paint should reduce dust exposure after surface preparation. Blast media reclaim, blowdown, masking, primer and topcoat areas should be arranged so cleaned steel does not cross raw fabrication traffic when the building allows it.
Air Systems For Long Workpieces
Long steel members need consistent exhaust and replacement air across the coating area. Duct routes, fan service points, make-up air discharge, compressed air and electrical feeds should be coordinated before equipment is set.
- Confirm maximum member length, weight, handling height and staging method.
- Identify crane columns, rails, roof structure, doors and existing duct routes.
- List coating steps, dry time needs and inspection hold areas.
Durable Access For Service
Steel finishing bays are hard on equipment surroundings. Filters, doors, lights, fans, controls, dampers and duct access should remain reachable after material racks and cranes are in use. Existing booths or blast rooms should be checked for worn seals, panel damage and duct condition before relocation.
Frequently asked questions
What should be ready before a structural steel site visit?
Have maximum steel dimensions, handling methods, coating steps, utility locations, crane limits, staging areas and any blocked-out production aisles ready for review.
Why does member length affect exhaust planning?
Long workpieces can require larger openings and longer coating zones, which changes exhaust volume, replacement air needs and service access around the booth.
Can blast and paint equipment share one bay?
They can be placed in the same larger area if the layout controls dust, traffic, utility routing and separation between prepared steel and dirty work.
What utilities are typical for steel finishing equipment?
Compressed air, electrical service, exhaust ductwork, make-up air, control wiring and gas for heated air where used are common items to review.
What matters when relocating a large steel booth?
Rigging path, panel condition, fan and duct condition, utility isolation, roof openings, new floor space and service clearances all matter.
