Custom equipment support rails
Rooftop Equipment Support
Custom fabricated equipment rails and support frames for rooftop HVAC equipment, fans, ducts, curbs, and field-mounted assemblies.
- Built to released dimensions, equipment layout, support spacing, and project-specific height or curb requirements.
- Typical construction uses galvanized sheet metal with formed sides, reinforced ends, internal supports, and custom bearing surfaces as quoted.
- Confirm roof condition, equipment load path, attachment requirements, and installation responsibility before release.

Construction Standard
| Application | Custom equipment rails and support frames for rooftop units, fans, duct runs, curb adapters, pipe or equipment supports, and mechanical equipment coordination. |
| Material | Galvanized steel is standard unless another material, coating, or finish is listed on the quote. |
| Construction | Rails are fabricated to released dimensions using formed galvanized components, reinforced ends, support webs, bearing flanges, and custom details as required. |
| Dimensions | Length, width, height, bearing surface, equipment spacing, roof slope, and field-fit requirements should be confirmed before fabrication. |
| Support details | Internal stiffeners, end caps, dividers, saddles, tabs, and attachment details can be included when shown or quoted. |
| Coordination | Rails are built from approved drawings, sketches, or verified field dimensions. Equipment weight, roof structure, fastening method, and engineering requirements are by others unless quoted. |
| Quality check | Rails receive visual inspection before release. Structural engineering, load certification, testing, or field acceptance are by others unless quoted. |

Fabrication Capabilities
| Rail sections | Straight equipment rails, support curbs, support saddles, rail sets, equipment bases, and field-fit rail sections. |
| Custom shapes | Offsets, stepped heights, pitched or sloped details, end closures, dividers, and special support profiles. |
| Reinforcement | Internal webs, braces, bearing plates, tabs, brackets, formed flanges, and special attachment details when requested. |
| Coordination | Equipment spacing, roof slope, curb height, attachment points, and piece-marked layouts can be coordinated before release. |
| Shop details | End caps, seams, drain or weep details, closures, shipping splits, labels, and hardware coordination as quoted. |
| Release support | Built from released dimensions, sketches, field measurements, or drawing packages with installation responsibilities clearly identified. |

Required for Quote / Release
- Rail length, width, height, quantity, and required field-fit or sectioned lengths.
- Approved drawing, sketch, roof/equipment layout, or verified field dimensions.
- Equipment size, support spacing, bearing surface, roof slope, curb height, and attachment requirements.
- Reinforcement, tabs, brackets, hole patterns, closure details, and piece-marking requirements.
- Material, coating, load/engineering requirements, shipping splits, and any inspection requirements.
Not Included Unless Quoted
- Installation, hoisting, rigging, roofing, roof penetration work, anchoring, or field fastening unless quoted.

Scope & Responsibility
Code note: Equipment rail assemblies may be governed by project specifications, structural requirements, roof warranty requirements, mechanical equipment requirements, local code, and AHJ direction. Empire fabricates rails to released dimensions and quoted scope; final equipment support design, load path, roof attachment, waterproofing, structural approval, installation method, and field acceptance remain the responsibility of others unless expressly included.
