Products Description
Our heavy duty metal angle brackets are right-angle support components specially designed for heavy structure connection and reinforcement. With 18 years of production experience in construction hardware stamping and welding, the products are widely used in European and American construction engineering, storage construction and heavy furniture manufacturing, and are a core essential product for local engineering purchasers and hardware channels.
Heavy duty metal angle brackets are formed by one-piece stamping of high-grade cold-rolled carbon steel or stainless steel, with reinforced welding for some large-size models. They have accurate right angles and excellent structural strength, can effectively disperse load stress at connections, prevent deformation or loosening of wood or steel structure frames, and greatly improve overall structural stability and service life. They are indispensable core connectors in heavy construction scenarios.

For the load requirements of different engineering scenarios, our heavy duty metal angle brackets cover multiple thickness and size series, with corresponding models from light furniture reinforcement to heavy factory construction. The products have pre-punched standard mounting holes; some models use slotted holes for fine adjustment of installation position, reducing on-site construction difficulty.
The surface can be treated with hot-dip galvanizing, electro-galvanizing, powder coating and other anti-corrosion processes. Among them, hot-dip galvanized models are especially suitable for outdoor and humid environments, with a rust prevention period of more than 10 years.
We support customers in customizing angle brackets with special sizes, thickened materials and custom hole positions according to project needs, and can also provide other matching construction hardware connectors to help customers achieve one-stop procurement.
At present, our heavy duty angle brackets are supplied in bulk to European and North American construction markets. With stable quality and accurate dimensions, they have earned continuous recognition from engineering customers, and export sales maintain steady growth.

Application Fields

Quality Control
We have established a special quality inspection system for construction hardware. All heavy duty metal angle brackets go through multi-node inspection from raw material incoming, including material verification, angle accuracy testing, stamping dimension verification, welding strength sampling, surface treatment adhesion testing, and 100% full inspection before finished product delivery.
We accept third-party material testing and load testing commissioned by customers. All products come with a 1-3 year warranty after delivery. If non-artificial quality problems such as deformation or coating peeling occur, free replacement is provided to fully ensure engineering construction quality and safety.
Payment Terms
We support FOB trade terms. For conventional standard orders, payment is 30% in advance with the balance settled against a copy of the bill of lading. For customized engineering orders, payment is 40% in advance with 60% balance settled against a copy of the bill of lading. We accept T/T payment in US dollars and euros.
Large-volume engineering procurement orders can enjoy tiered price discounts. Long-term cooperative channel agents can apply for more flexible payment terms to effectively reduce capital turnover pressure.
Customization Capability
We fully support OEM/ODM customization services. Customers can provide drawings or samples to customize heavy duty angle brackets with different side lengths, thicknesses and hole layouts, and can also customize exclusive logos and engineering packaging.
Custom orders include free prototyping with a 30-45 day sample cycle; customers only pay for international express delivery. After sample approval, mass production can be arranged. During production, we operate a 24-hour shift system to ensure a standard delivery cycle of 30-45 days. Repeat orders receive priority production scheduling to further shorten delivery time.
