Custom Sheet Metal Mounting Brackets
Sheet metal mounting brackets set where a housing, manifold, or panel sits on a frame, so each flange face has to seat square. K-Display makes L, Z, U, and offset brackets and gusseted, welded assemblies to your model.
Sheet metal brackets we build
We cut and form L, angle, Z, offset, and U brackets from aluminum, carbon steel, galvanized steel, galvannealed steel, or stainless steel, and weld gussets and joints in carbon steel, stainless steel, or aluminum. Brackets ship loose, as welded assemblies, or powder coated with self-clinching hardware installed. Flat parts that carry a hole pattern are Mounting & Backing Plates, and small brackets for a sensor or a cable run are Cable & Sensor Brackets.
The vertical flange bolts to the post and the horizontal flange carries the housing, so each flange has its own hole pattern and its own job. The gusset under the shelf holds the two at the angle the housing needs.
Brackets we make
- L, angle, and corner brackets
- Single-bend and multi-bend brackets cut and formed from your flat pattern or model, with self-clinching nuts and studs pressed in where a flange is too thin to tap.
- Z, offset, and U brackets
- Offset, joggle, and channel forms that step a component off a surface or straddle a member.
- Gusseted and welded brackets
- Brackets stiffened with welded gussets or formed return flanges, or joined from several pieces where one bend cannot reach the geometry, including brackets that carry a manifold or a small housing.
Bend geometry and weld distortion
- Holes near a bend
- Metal stretches at a bend, so a hole or slot placed too close distorts and moves off its position. How close a feature can sit depends on the material, thickness, and forming tooling.
- Flange length and radius
- Short flanges and tight radii limit which tooling can form the part. On Z and U forms, step height and channel depth also depend on tooling clearance, so a tighter step changes the form.
- Gussets and welds
- A weld beside a datum face pulls that face out of square as it cools, and a mounting face that moves no longer seats the component.
- Coating on seating faces
- A coat of powder has thickness, so a component clamped to a coated flange sits a coat higher than the drawing shows, and a hole a bolt cleared bare can bind.
Sequence for a formed bracket
A fastener under a return flange or inside a channel goes in before the bend, because the press cannot reach it afterward.
Cut the flat pattern
We laser cut the flat pattern from your model.
Form and weld
We press in any hardware that forming would close over, form the flanges on tooling suited to the material and radius, and weld gussets and joints.
Finish and ship
We press in the remaining fasteners, mask threads and bare faces, powder coat, and ship the bracket loose, as a weldment, or coated with hardware installed.
Check the formed interface
Identify the frame face and the component face on the drawing, then mark the hole positions that connect them. Those are the relationships to check on a formed first part, including any weld or coating that affects how the bracket seats.
The hole patterns on both flanges must meet their mating parts after forming. Bend angle and flange position connect those patterns, so checking the flat holes alone cannot establish the finished fit.
What to send for a bracket quote
- Model or drawing
- STEP or DXF with a marked PDF of the critical dimensions, and the material grade, temper, and thickness.
- Mounting interface
- The component, the frame or panel it mounts to, fastener sizes, and which holes locate the bracket and which are clearance.
- Hardware
- Fastener part numbers and who supplies them.
- Finish
- Coating color and texture, faces that stay bare, and whether hole sizes apply before or after coating.
- Order size
- Quantity, delivery date, and any inspection requirement.
