Sheet Metal Fabrication for Construction
Construction sheet metal fabrication at K-Display includes door sections, rolling-door hoods, operator and gate housings, dock covers, and equipment guards. The parts go to makers of overhead doors, gate operators, and dock equipment, and to builders of construction machines.
Door, hood, housing, and guard parts for construction OEMs
Overhead doors, gate operators, dock equipment, and construction machines put sheet metal around a curtain, a drive, a leveler, or an engine. K-Display cuts and forms door sections, rolling-door hoods, operator housings, dock covers, and machine guards from pre-galvanized sheet, installs the hardware, and powder coats each part. Sheet to ASTM A653 in G90 carries at least 0.90 oz/ft² of zinc, both sides combined, and G60 carries 0.60, so the designation you choose for construction sheet metal fabrication sets how much zinc lies under the powder coat.
The curtain rolls up behind the hood, so the hood's depth and front lip mark the edge of the space the door moves through. Hoods and covers are formed to keep their metal outside that space.
What we make for construction
- Door section components
- Formed panel parts, end stiles, and reinforcement channels for sectional doors, with the strut and hinge attachment holes for each door model.
- Rolling-door hoods, covers, and mounting plates
- Formed hoods, guide covers, and bracket plates, with the hole pattern for the door's end brackets.
- Garage door brackets and plates
- Formed brackets, mounting plates, and reinforcement parts, punched and bent to the orientation the door hardware needs.
- Operator and control housings
- Housings, control boxes, and removable covers for door operators, with drive clearance and wiring entries.
- Gate and access-control enclosures
- Pedestals, reader housings, and cabinets for vehicular gate operators and access-control equipment.
- Dock equipment covers and brackets
- Covers, backing plates, and brackets for the makers of dock levelers, seals, and vehicle restraints, formed from galvanized sheet.
- Equipment guards, covers, and brackets
- Light-gauge guards, engine and hydraulic covers, and mounting brackets for construction machines such as loaders and excavators.
What construction jobs require
- Galvanized coating designation
- ASTM A653 designation, G60 or G90, or galvanneal, for each part.
- Thickness in decimals
- Actual steel thickness as a decimal, not a gauge number, as DASMA advises, because a gauge number describes only the unembossed galvanized skin.
- Exposure
- The sun, rain, salt, or wash conditions the part sees in service, which decide the powder coat system over the galvanized surface.
- Powder coat color and gloss
- The color and gloss over the galvanized surface, with the faces that show in the installed door or machine.
- Mating geometry
- Hole pattern, edge distance, and drawings of the parts each component joins, such as the end bracket a hood bolts to.
- Wind-load option
- The wind-load option of each door model, which sets the struts and reinforcement channels.
Tolerances on the hood's end-flange holes add to those on the bracket's holes across the joint. Both pairs are dimensioned from the flange edge, and only that one edge feeds the tolerance.
How construction work runs
Cut and form the blanks
We laser cut or punch pre-galvanized and galvanneal sheet, then press brake form the bend angles and flange lengths.
Fit hardware, mask, and powder coat
We install the hardware first, mask its threads and the mating faces, and then powder coat.
Kit, label, and pack
We supply parts loose or kitted door by door, labeled by door model and packed for each release, with each kit listed against your bill of material.
