Sheet Metal Ventilation Bracket — Custom Sheet Metal Fabrication Manufacturer
SHENZHEN BENXIN ELECTRONIC HARDWARE CO., LTD
Product Details
Keywords: sheet metal fabrication, custom metal brackets, ventilation bracket, sheet metal enclosure, metal chassis, laser cutting service, custom sheet metal parts
Product Overview
This hot-selling black bracket is a classic example of efficient sheet metal design: one bent piece of steel forms a U-shaped structure with a full pattern of ventilation slots, folded mounting flanges and pre-punched holes. It cools, protects and mounts equipment in a single component — exactly the kind of fabricated part we produce at scale for electronics, appliances and industrial machinery.
Key Features
Single-piece bent construction — U-shaped body formed from one sheet for strength and economy
Full ventilation pattern — stadium-shaped slots punched across all panels for airflow and heat dissipation
Integrated mounting flanges — folded 90° edges with pre-drilled holes for fast assembly
Matte black powder coating — durable, scratch-resistant finish that suits equipment interiors
Clean punched holes — no burrs, ready for rivets, screws or standoffs
Applications
Used as protective cages, fan brackets, chassis inserts and mounting frames in electronics cabinets, power supplies, servers, appliances and industrial control equipment.
Manufacturing & Factory Capability
Produced end-to-end in our sheet metal workshop:
Fiber laser cutting — precise blanks from SPCC, SGCC, stainless and aluminum sheets
CNC punching & forming — slot patterns and 90° bends on CNC press brakes with repeatable angles
Welding & assembly — spot welding and hardware insertion available
Powder coating line — black, grey and RAL colors with pretreatment for adhesion
In-house tooling — dies and fixtures for stable batch production
Customization & OEM/ODM
Send us your drawing or a sample: we adjust size, slot pattern, hole positions, thickness (typically 0.8–3.0 mm), material grade and finish. Small-batch prototyping and large-volume production both supported.
Quality Assurance
Bend angles, hole positions and coating thickness are checked per batch; flatness and burr control verified before packing.

We support DHL, FedEx, TNT, sea freight, and can do DDP / DAP terms.
- Is there a minimum order quantity (MOQ)?
We have no strict MOQ. We accept prototype trial orders as low as 1 piece. - How can I get an accurate quotation?
Please send us your 3D STEP/IGES file, 2D drawing with tolerance, material requirement, quantity and surface finish. - Can you help with DFM optimization?
Yes. Our engineers provide free DFM suggestions to reduce machining cost and improve manufacturability. - How long is the quotation valid?
Quotation is normally valid for 30 days, subject to raw material price fluctuation.
Pricing depends on material, dimensions, tolerance, quantity and surface finish. Please send your drawings (PDF/DWG/STEP/IGES) and we will provide an exact quote, usually within 24 hours.
The price is based on material cost + machining time + surface treatment + tooling (if any) + packaging and freight.
Our standard quotes are FOB Shenzhen/Dongguan unless otherwise stated. Air or sea freight can be quoted separately according to your destination.
Our price reflects the material grade, tolerance level, full inspection and finishing quality. If needed, we can suggest cost-saving design changes (e.g. relaxing non-critical tolerances) to reduce the cost.
Yes. We provide tiered pricing — the unit price decreases as the quantity increases. Please tell us your target quantity for the best price.
