Sheet Metal Parts
Custom Sheet Metal Brackets
Custom sheet metal brackets made from approved drawings and formed CAD files. Submit material, thickness, quantity, critical bend dimensions and finish requirements for RFQ review.
YSBK manufactures custom sheet metal brackets from customer-approved drawings and CAD files for industrial equipment, automation and engineering projects.
For quotation, provide the current 2D drawing and matching formed STEP model where available. The RFQ should define the material grade, sheet thickness, quantity, critical dimensions after bending, finish requirements and inspection scope.
A bracket name, photograph or incomplete flat pattern alone is not sufficient for production quotation. Any conflict between the drawing, formed model and flat-pattern file must be resolved before manufacturing.
Custom Bent Brackets Made From Customer Drawings
Typical made-to-drawing parts include:
• mounting brackets;
• offset and stepped brackets;
• angle brackets;
• equipment supports;
• brackets with bent flanges;
• brackets with holes or slots on different faces;
• tabs and locating features;
• small sheet metal assemblies defined by released manufacturing files.
These are not standard catalogue brackets. Their dimensions, bend geometry, hole pattern, material and finish are controlled by the customer’s approved files.
When a bracket requires machined pockets, precision bores or substantial material removal instead of primarily cutting and bending, see our Custom CNC Machined Brackets page.
What to Send for a Sheet Metal Bracket RFQ
Please provide:
• the latest approved 2D drawing;
• a formed 3D CAD or STEP model, where available;
• the flat-pattern file, if it is a controlled manufacturing requirement;
• part number and drawing revision;
• exact material grade and sheet thickness;
• quantity for each part number;
• critical dimensions and tolerances after bending;
• hole, slot and thread requirements;
• bend direction and relevant bend geometry;
• finish, color, texture and masking requirements;
• inspection documents required with delivery;
• target delivery date.
The 3D model communicates the intended formed geometry. The 2D drawing should define tolerances, datums, threads, surface requirements and acceptance criteria that may not be fully communicated by the model.
Critical Dimensions After Bending
A flat blank may meet its cutting dimensions while the finished bracket still fails to fit the assembly after bending.
The drawing should identify the dimensions that control the bracket in its final formed condition. Examples include:
• mounting height;
• offset between two mounting surfaces;
• flange position;
• angle between formed faces;
• hole or slot location after bending;
• spacing between features on different faces;
• clearances around adjacent equipment;
• contact or locating surfaces.
For stepped brackets or features distributed across several faces, clearly define the reference surfaces used for inspection.
Do not rely only on the flat pattern to communicate finished-part acceptance. If the flat pattern, formed model and 2D drawing represent different revisions, the controlling file must be confirmed before production.
YSBK does not select between conflicting design files without customer confirmation.
Holes, Slots and Features Near Bends
Holes, slots, cutouts and tabs positioned near a bend can be affected by the forming sequence and surrounding geometry.
The manufacturing review considers:
• the distance between a feature and the bend;
• whether a hole or slot is controlled before or after forming;
• tool access;
• the relationship between features on different faces;
• whether the finished mounting position is more important than the flat-blank location;
• edge and deburring requirements.
Where assembly position is critical, define the finished reference surfaces and the required location after bending.
Material Grade and Sheet Thickness
Specify the complete material grade and nominal sheet thickness in the RFQ.
Material availability and suitability for the submitted geometry are reviewed per order. YSBK will not substitute a material grade or thickness without customer approval.
If the assembly requires a particular material condition, certificate, batch record or traceability document, state that requirement before quotation.
Material certificates and lot-traceability documents are issued by raw-material suppliers. These documents must be confirmed per order during RFQ and are not automatically included with shipment.
Finish, Color and Masking Requirements
For finished brackets, specify the required surface treatment and any applicable:
• color;
• gloss or texture;
• visible-surface requirements;
• masking areas;
• electrical-contact areas;
• grounding points;
• threaded or mating features that must remain uncoated;
• critical dimensions that must be checked after finishing.
A photograph can be used as an appearance reference, but it does not replace a written finish specification.
Finishing availability, cost, lead time and the required delivery condition are evaluated during RFQ. The quotation should clearly state whether the parts will be supplied unfinished or with the specified finish completed.
Inspection and Documentation
Basic dimensional verification uses calipers, micrometers, depth gauges and height gauges.
Inspection follows the agreed drawing and focuses on the features identified for the project. For formed brackets, these may include mounting height, offsets, hole and slot locations, flange position and finished interfaces.
YSBK does not have in-house CMM or optical inspection equipment.
Full-dimensional reports, CMM reports, first-part photographs and key-dimension records are not provided by default. Any required photographs, recorded dimensions, sample quantity or inspection condition must be agreed during the RFQ stage.
Inspection verifies the agreed part features against the released manufacturing files. It does not validate the bracket within the customer’s complete machine or assembly. Design approval and assembly validation remain the customer’s responsibility.
Prototype, Low-Volume and Repeat Orders
MOQ is one piece. We support one-off brackets, engineering samples and low-volume production quantities.
For a prototype intended to approve a repeat batch, submit the production-intent material, finish and inspection requirements from the beginning.
A manual change made during fitting or assembly does not automatically become a production requirement. Update the drawing and CAD files before repeat production if the approved design has changed.
For repeat orders, confirm:
• the current drawing revision;
• quantity;
• material and thickness;
• finish;
• inspection scope;
• any changes made after the previous delivery.
Quotation timing depends on drawing completeness, material sourcing, geometry, finishing and inspection requirements.

Frequently Asked Questions
Can you quote a sheet metal bracket from a STEP file only?
A STEP file can communicate the formed geometry, but it may not define material grade, sheet thickness, tolerances, threads, finish, masking or inspection requirements. Provide a matching 2D drawing or written manufacturing requirements where these details apply.
Should I provide the flat pattern?
You may provide a flat pattern, but identify whether it is a controlled manufacturing requirement or a reference file. The formed model and drawing must use the same revision. Any conflict must be resolved before production.
Which dimensions should be inspected after bending?
Identify the dimensions that control assembly in the finished condition, such as mounting height, offsets, flange position and hole or slot locations across different faces. Do not assume that checking the flat blank alone confirms the formed bracket.
Can you manufacture one prototype bracket?
Yes. MOQ is one piece. Material availability, finishing and inspection requirements are reviewed during RFQ.
Are dimensional reports included automatically?
No. Full-dimensional reports, first-part photographs and key-dimension records are not included by default. Define the required dimensions, number of parts to measure and documentation format during RFQ.
Will you change the material grade or thickness if the requested stock is unavailable?
No substitution should be made without customer approval. Material grade, thickness and availability are confirmed during RFQ.
