30×28 Electro‑Galvanized L‑Shape Punched Metal Bracket, Strut Channel Fitting for HVAC and Pipe Hanging Systems
Product Description:
This 30×28 L‑shaped punched metal bracket is a modular supporting fitting built for flexible field assembly and good compatibility with strut channel systems. Fabricated from premium Q235B carbon steel and finished with uniform electro‑galvanized treatment, it delivers reliable anti‑corrosion performance and low‑maintenance properties. Pre‑fabricated oblong slotted holes match most standard strut‑channel hardware, supporting fast installation, position adjustment and on‑site re‑arrangement to adapt to changing project layouts.
Commonly deployed for HVAC duct supports, pipe hanging, electrical cable routing and general building‑construction applications. The high‑strength steel substrate realizes even load dispersion. Custom hole pitches and dimensional options are available to satisfy special design requirements. We support full‑range customization including custom overall dimensions, hole layouts and surface finishes. Strict factory quality inspection plus export‑standard packaging enables worldwide sea shipment, complying with international product‑quality requirements.

Applied range:
Within mechanical and industrial engineering fields, this 30×28 perforated L‑bracket serves as a multi‑purpose supporting component for multiple core systems. It is widely adopted inside HVAC and plumbing projects as pipe hangers, duct supports and equipment mounting brackets. Pre‑punched slots allow flexible position tuning for pipes and ducts, accommodating layout adjustments without expensive secondary processing.
For electrical rooms and data‑center facilities, it acts as key supporting hardware for cable trays and wiring harnesses, forming solid mounting frameworks for power and communication cables while keeping convenient access for routine maintenance.
Additionally, these L‑shaped brackets are extensively used in manufacturing plants and automation workshops to hold conveyor frames, machine bases and production‑line assemblies. Thanks to decent mechanical strength and electro‑galvanized anti‑rust coating, they can endure continuous vibration, moisture and chemical exposure inside factories, warehouses and processing workshops. Modular‑style construction guarantees good interoperability with mainstream strut‑channel accessories for seamless integration into various industrial setups.
