01 / What We Fabricate
The Sheet Metal Parts Inside HVAC Equipment
HVAC OEMs often release fan decks, drain pans, coil panels, baffles and serviceable hardware as a mixed sheet metal package beyond the main RTU enclosure, duct or plenum.
Drainage Components
Condensate pans, drip trays, drain slopes and splash-control parts with formed corners and outlet features.
Coil and Service Panels
Coil end panels, filter frames, access covers and removable service panels with controlled cutouts and hardware.
Platform Component Kits
Mixed supports, panels, trays and hardware grouped by HVAC model, module and released drawing revision.
Our scope: the released HVAC mechanical component package
DRAmetal manufactures fan decks, drain pans, coil and access panels, supports, brackets and hardware-ready kits. The HVAC OEM owns airflow and refrigeration design, fan and coil selection, drainage validation, controls, electrical safety and final equipment certification.
02 / HVAC Component Types
Fan Decks, Drain Pans, Panels and Installation Kits
Each part family is controlled around the interface it serves: fan alignment, condensate drainage, coil access, filter fit or final equipment assembly.
Airside Fan Decks and Equipment Supports
Formed decks, motor plates, rails and brackets supporting fans, blowers and internal equipment modules.
- Materials Galvanized / coated steel
- Control Hole and flange datums
- Use Fan and blower modules
Drainage Condensate and Drip Pans
Stainless, galvanized or aluminum drain pans with welded corners, formed slopes, outlets and protected sealing areas.
- Materials SS / galvanized / aluminum
- Features Slope and drain outlet
- Inspection Fit and water-path check
Service Coil, Filter and Access Panels
Coil end plates, filter frames, service covers and removable panels with repeated cutouts, edge safety and hardware fit.
- Features Cutouts and inserts
- Control Service clearances
- Finish Drawing-defined
Kits HVAC Mounting and Hardware Kits
Bracket sets, rails, shields, panels and installed hardware packed by equipment model or assembly station.
- Scope Mixed component family
- Quality Hardware presence
- Packout Model and revision

04 / Manufacturing Process
From HVAC Platform BOM to Assembly-Ready Kits
01
Platform Boundary Review
Separate fan, coil, drainage, service and enclosure interfaces and confirm the released component list.
02
DFM and CTQ Mapping
Review bend access, drain slope, weld sequence, hardware, coating, gasket areas and assembly-critical datums.
03
Cutting and Forming
Cut, punch, bend and roll panels, pans, decks, rails and brackets with part and revision identity maintained.
04
Joining and Hardware
Fixture-weld corners and supports, then install inserts, studs, nuts, hinges or specified mechanical hardware.
05
Functional Interface Checks
Inspect fan and coil holes, pan slope and outlet, access-panel fit, hardware, edges and finish condition.
06
Model-Based Packout
Group mixed components by HVAC model, module, assembly station and drawing revision.
05 / Why It Matters
Why Mixed HVAC Components Need Platform-Level Control
A drain pan, fan deck and service panel can each pass loose-part inspection while the assembled unit still leaks, binds or misaligns. Controls need to follow the actual equipment interfaces.
Fan and Coil Alignment
Mounting holes and support flanges must locate rotating and heat-exchange equipment without forcing the assembly.
Drainage Geometry
Pan slope, welded corners and outlet location must preserve the intended condensate path after fabrication.
Service Access
Panels, filter frames and covers must remain removable with the specified hardware and adjacent components installed.
Variant Control
Similar-looking parts across HVAC capacities and model revisions need unmistakable traveler and packout control.

Why HVAC OEMs Use DRAmetal for Component Families
01
Mixed-part manufacturing
Pans, decks, panels, rails, brackets and hardware can be coordinated under one platform release.
02
Interface-focused DFM
Drainage, rotating equipment, service access, insulation and coating interfaces are reviewed before release.
03
Integrated fabrication flow
Cutting, forming, welding, finishing, hardware insertion and mechanical kitting are managed together.
04
OEM assembly packout
Components can ship by equipment model, module, station and revision to reduce line-side sorting.

09 / FAQ
HVAC Sheet Metal Components FAQ
Which HVAC sheet metal parts can DRAmetal manufacture?
Typical parts include fan decks, motor plates, condensate pans, drip trays, coil and filter panels, service covers, rails, brackets, shields and hardware-ready kits.
How is this different from your HVAC enclosure page?
The HVAC enclosure page covers the complete outer cabinet or casing. This page covers the internal, drainage, support and service components installed within that equipment platform.
Can you fabricate stainless condensate pans?
Yes. Stainless, galvanized and aluminum pans can be formed and welded to released drawings with drain outlet, slope, corner and fit checks defined in the inspection plan.
Can mixed parts be packed by HVAC model?
Yes. Fan, drain, coil, service and bracket parts can be identified and packed by model, module, assembly station and drawing revision.
What should an HVAC component RFQ include?
Send drawings, 3D models, BOM, material and coating notes, fan and coil interfaces, drain requirements, hardware, CTQs, model variants, prototype quantity and annual volume.
