What to Confirm Before Ordering Supports and Brackets
Supports and brackets in a facility package are small parts with fixed interfaces. Confirming the interfaces before ordering avoids the fit problem later.
A bracket is cheap to make and expensive to get wrong, because it usually connects two things that were designed separately. The confirmation work before the order is mostly about those two connections.
The interface at each end
Every support has at least two. Describe both.
- What it fixes to: a stud pattern, a cast in embed, a strut channel, a welded plate, a concrete surface. Each has a different hole requirement, and the drawing should say which one applies.
- What it carries: the equipment foot, the pipe clamp, the tray, the panel. The bracket geometry follows from this, and the mounting height is usually the dimension that matters.
- Whether adjustment is required. A slotted hole is a different part from a round one, and a slotted hole is usually there because the interface is not exact.
Hole patterns and threads
Give the hole size and position, and the thread where a hole is tapped. On the plate table, drilling, tapping, counterboring and milling run in the same setup as the cutting, so a tapped hole specified at quote does not become a second operation.
Confirm which hole group is the datum. A bracket with two hole groups and no datum is a bracket with two possible orientations.
Coating and the interface
If the component is powder coated, decide which surfaces stay bare. A bracket that mounts to a coated surface with a coated mating face loses contact and can crush the finish. Masking is a decision that belongs in the order, not in a conversation after coating.
Quantities and repeats
State the number and whether the part repeats across an area, a floor or a building. Repeats change how the part is programmed and whether a fixture is worth building, which is the subject of quoting repeated components for a data center project.
The responsibility boundary
This is the part worth being explicit about. KorFab cuts, forms, drills and welds to the drawing supplied. It does not approve the support design, certify a load, or take responsibility for the system the bracket belongs to. Those decisions sit with the responsible design team, and an order that assumes otherwise will stall at the approval stage.
What the shop does confirm is whether the part can be made as drawn, and what it takes to do it.
The confirmation list
Interface at both ends, hole patterns with a datum, coating and masking, quantity and repeats, and who owns the design. Five items, each of which is cheaper to settle before the order than after.
