Custom Steel Welded Bracket Structural Bearings

Product Introduction

This is a steel brackets used in construction industry. There are a lot of different types bracket. In construction, steel brackets undergo processes like hot-rolling, cold-forming, or welding to achieve precise geometries, often followed by surface treatments to enhance corrosion resistance. With standardized manufacturing and strict quality control, steel brackets ensure the safety and stability of construction projects, balancing performance with economic efficiency.

Material and process

This product is made of weld tubes, which are cut into pieces.

The tube still need to drill the hole on the side surface, flat-head chamfer, and deburr to remove burrs and ensure smooth edges. 

The plates are hot-rolled plates, cut by punch presses. Argon arc welding is employed to join tubes and plates, with weld seams requiring a minimum thickness of 6.35mm to meet structural strength requirements.

Finally components undergo hot-dip galvanization. Post-galvanization, natural surface flow marks are acceptable, eliminating the need for additional grinding.

The key points for this bracket lie in：

1. Ensuring the material wall thickness meets standards, inadequate thickness compromises load-bearing capacity, especially for structures subject to dynamic loads or heavy weights. 

2. The welding seams are sufficiently wide and full, Argon arc welds must achieve a minimum width of 6.35mm with uniform, non-porous fusion. Visual inspection should confirm no undercutting, slag inclusions, or lack of penetration

3. The hot-dip galvanization is properly executed. Ensure no bare metal spots, with natural flow marks from galvanization accepted as long as they do not compromise the coating’s integrity. Avoid mechanical grinding that could thin the zinc layer.

Packing

We systematically place the products into cartons and then palletize them, ensuring order and stability throughout the process. Each product is arranged neatly in the carton to prevent shifting during transportation, and dividers or protective materials may be used when necessary to avoid collision. The cartons are then stacked on pallets in an organized manner, secured with stretch film and corner protectors to maintain structural integrity, ensuring the goods remain intact from warehousing to delivery.
