Product Introduction

Product Advantages

Perforated Angle Bar has many advantages over other types of beams, such as:

It can be used as a framing member, a shelf support, a corner brace, a reinforcement, or a connector, depending on the orientation and hole pattern.
It can be easily adjusted and modified, as the holes allow for flexible and convenient installation and adjustment of bolts, screws, nuts, and other fasteners.
It can reduce the weight and cost of the structure, as the holes reduce the material consumption and increase the strength-to-weight ratio of the beam.
It can improve the ventilation and lighting of the structure, as the holes allow for air circulation and light penetration.

Usage

Perforated Angle Bar is easy to use and install, as they can be welded or bolted to other structural elements. However, some precautions and instructions should be followed to ensure the quality and safety of the installation, such as:

The welding of Angle Bar should be done by qualified welders, following the appropriate welding procedures and codes.
The bolting of Angle Bar should be done with high-strength bolts, following the specified torque and tightening sequence.
The base plates of Angle Bar should be properly anchored to the foundation, using suitable anchor bolts and grout.
The alignment and plumbness of Angle Bar should be checked and adjusted before and after the installation, using appropriate tools and methods.

Slotted Angle Bar is not only functional, but also aesthetic. They can be painted or coated with different colors and finishes, according to the design and preference of the customers. However, some protection measures should be taken to prevent corrosion and deterioration of the steel, such as:

The surface of Slotted Angle Bar should be cleaned and prepared before painting or coating, removing any dirt, rust, oil, or grease.
The paint or coating of Perforated Angle Bar should be applied in accordance with the manufacturer's instructions and specifications, ensuring adequate coverage and thickness.
