Galvanized Steel Angle

Galvanized Steel Angle is a steel material that has been galvanized and covered with a layer of zinc. This galvanizing process is usually achieved by dipping the angle steel into molten zinc or using electroplating technology. It not only enhances the corrosion resistance of the steel but also gives it an aesthetic appearance. It not only has a long service life but is also easy to process. In addition, it is relatively easy to buy and is a low-cost structural steel, so it is deeply loved by various industries. Which is available for sale at Wanzhi Steel.

Classification of gi angle steel

Classification by process

It can be divided into hot-dip and cold-dip angle steel.

1. Hot-dip galvanized angle steel: It immerses the angle steel in high-temperature molten zinc liquid to make the zinc layer adhere to the surface of it.

2. Cold-dip galvanized angle steel uses the electrochemical principle to ensure full contact between zinc powder and steel, generating electrode potential difference for corrosion protection.

Classification by side length

It can also be divided into galvanized equal-leg angle steel and galvanized unequal-leg angle steel.

The two vertical sides of the same length are equal-leg angle steel, while the ones with one longer and one shorter are unequal-leg angle steel.

Name	Side length (cm)
Large angle steel	>12.5
Medium Angle Steel	5-12.5
Small angle steel	<5

Hot dip galvanized equal-angle steel

Hot-dipped galvanized equal leg angles are excellent candidates for most processing techniques. Welding, torching, or abrasive sawing galvanized steel is not recommended without proper protection and adequate ventilation.

Galvanized angles are A36 hot rolled steel, or mild steel, angles that have been dipped into a molten zinc coating process (ASTM A123).

Hot-dipped galvanize

Hot-dipped galvanize (HDG) can be identified by its crystallization pattern, also known as “spangle” on the surface of the material. Galvanized angles have round or tapered edges. Great corrosion resistance, an excellent candidate for outdoor use or exposed environments. Common applications include heating and cooling systems, mounting brackets, structural support, trailers, and docks.

Wanzhi gi angle steel weight calculation

The weight of galvanized angle steel is the same as the calculation formula of angle steel weight.

The weight of angle steel per meter = 0.00785*(edge width + edge width-edge thickness)*edge thickness, in centimeters.

The total weight of each piece = the weight of angle steel per meter*length, that is 0.00785*(edge width + edge width-edge thickness)*edge thickness*length.

What is galvanized angle steel?

Galvanized angle steel is an angle steel with a layer of zinc on the surface of ordinary angle steel. It is a popular building material, mainly used to provide structural support and prevent steel corrosion, thereby increasing the service life of steel.

What is a steel angle?

Steel angle, also named angle iron, or steel angle bar, is manufactured by hot-rolled carbon steel or strength low alloy steel. It has an L-cross-shaped section with two legs – equal or unequal and the angle would be 90 degrees. The specifications are expressed in millimeters of edge width × edge width × edge thickness.

Advantages of gi angle steel

1. Anti-corrosion performance and durability: It can resist harsh environments such as moisture and acid rain, and is not afraid of outdoor high temperature, humidity, and corrosive environments.

2. Strength and stability: It has very high strength and is not easy to deform. It is a very stable building material.

3. Plasticity and processability: It can be bent and cut as needed, and can be cut and welded into various shapes and sizes.

4. Fireproof and lightning protection characteristics: It has fireproof and lightning protection characteristics, so it is very popular in the fields of construction and engineering.

5. Lower cost: Compared with other corrosion-resistant materials such as stainless steel, the cost of galvanized angle steel is relatively low and more economical.

6. Wide range of applications: Such as construction, automobile manufacturing, home appliances, and furniture manufacturing, and has strong adaptability.

 

Galvanized Steel Angle and Hot-dip GI Steel Angle

In essence, they are all galvanized angle steels, but galvanizing is a general term that can include different galvanizing processes (such as hot-dip galvanizing, electro-galvanizing, etc.).

1. Hot-dip galvanizing specifically refers to the hot-dip galvanizing process, which produces a thicker coating, generally 30-60 microns, with higher corrosion resistance.

2. Electro-galvanizing (cold-dip galvanizing) has a thinner coating and may not be as corrosion-resistant as hot-dip galvanizing.

Regardless of the process, the two may differ slightly in appearance, but they usually present a smooth, bright metal surface.

Application of galvanized angle steel

Construction industry – Roofs, walls, doors and windows, high-voltage transmission towers

Automobile manufacturing – used in various structures and components, frames

Home appliance and furniture manufacturing – external machine brackets, connecting fasteners, beams, flower pot racks, solar racks, etc.

Others – Bridges, crane columns and booms, ships, reaction towers, container racks, fences.
