L-shape Steel: Weight Chart, Mass, Standards

Unequal angle steel, commonly referred to as L-shape steel, is a type of building material with unique characteristics and diverse applications in various industrial and construction sectors. The special feature of L-shape steel compared to other types of steel is its two unequal edges, forming a right angle. Let’s explore this special type of steel with Stavian Metal. Learn about the specific information of L-shape steel and its application in the article below.

L-shape steel, the most widely used building material in every project

Understanding L-shape Steel

Unequal angle steel, or L-shape steel, is a type of steel product designed and manufactured in the shape of an “L”. The common characteristic of this type of steel is having two unequal edges forming a right angle. L-shape steel is highly regarded for its hardness, strength, and durability, especially in applications requiring high resistance such as in bridge construction and industrial projects.

L-shape steel is also known as unequal angle steel

L-shape steel is often preferred in projects that require high load-bearing capacity due to its high pressure and vibration resistance. Although similar in shape to V-shape steel, these two types of steel still have distinct characteristics and applications.

In particular, the flexibility and adaptability of L-shape steel have made it an essential and indispensable material in the construction and mechanical industries.

Common types of L-shape steel

L-shape steel is a widely used material in many types of projects, thanks to its ability to withstand high pressure and harsh weather conditions. Below are the common types of L-shape steel:

Galvanized L-shape steel

The tropical humid climate in Vietnam creates favorable conditions for the formation of rust and corrosion in metal materials. Galvanized L-shape steel was born to solve this problem. Galvanized L-shape steel has a zinc coating layer that helps prevent rust and increase the lifespan of the material.

There are three common types of L-shape steel on the current market

Hot-dip galvanized L-shape steel

Hot-dip galvanized L-shape steel is produced through the hot-dip galvanizing process. The outer zinc coating protects the material from negative environmental effects after production.

Black L-shape steel

Black L-shape steel has a black or dark blue color due to the cooling process with water spray during the steel rolling process. It is widely used in practice with high popularity.

The above types of L-shape steel all have their own applications and characteristics, suitable for the needs and requirements of specific projects.

Each type of L-shape steel has its own advantages and disadvantages suitable for different types of projects

Standards and specifications of L-shape steel in the market

Unequal angle steel is produced according to various standards to meet the usage needs and diversity of different types of projects. Below are some common grades of L-shape steel available on the market today:

• Russian steel grades: CT3 and others, comply with GOST 380-88 standard.
• Japanese steel grades: SS400 and others, according to JIS G3101, SB410, 3010 standards.
• Chinese steel grades: SS400, Q235B, and others, following JIS G3101, SB410, 3010 standards.
• American steel grades: A36 and others, comply with ASTM A36 standard.

Each steel grade has different prices depending on the origin, quality, and production standards. Among these, Chinese steel grades are the most commonly used due to their reasonable prices, diverse designs, and easy availability on the market.

Real-life applications of L-shape steel

L-shape steel, with its outstanding advantages, is applied diversely in various industries and fields. Specifically:

• Civil and industrial construction: L-shape steel is widely used in the construction of civil and industrial projects. It is often chosen as an ideal material for chemical plants, water and oil pipelines, and many other applications.

• Bridge structures and transportation projects: L-shape steel bars are integrated into bridge structures, warehouses, ships, ferry terminals, and other transportation projects. Its variety in size and load-bearing capacity makes L-shape steel a top choice in constructing structures with requirements for durability and stability.

• Industrial and manufacturing: In industrial and manufacturing sectors, L-shape steel bars are also widely used for engineering purposes, from basic machine structures to materials in the production process.

The lightweight and high load-bearing capacity of L-shape steel are important factors contributing to its flexibility and diversity of applications in various projects and industries.

Sizes of L-shape Steel

L-shape steel comes in various sizes to serve different purposes in construction projects. Each project has its own technical requirements, and therefore will use L-shape steel with appropriate dimensions.

The variety of sizes allows designers and engineers to choose the most suitable type of L-shape steel for the specific needs of each project. This helps optimize flexibility and efficiency in constructing structures from small to large.

Calculating the mass of L-shape steel, weight chart of L-shape steel

Detailed formula for calculating the mass of L-shape steel

Example of the specification symbol of hot-rolled L-shape steel: L-shaped steel with dimensions of 60x40x5, named L60x40x5B according to TCVN 1657 – 1993 standard.

The cross-sectional area is calculated by the formula:

S=[t(A+B−t)+0.2416(R2 −2r2)]×1/100

Where:

• A: the larger flange width
• B: the smaller flange width
• t: the thickness of the flange
• R: the inner radius
• r: the flange radius

The mass of 1m length is calculated based on the nominal size and mass of L-shape steel, with a value of 7.85 kg/dm^3.

The formula for calculating the mass of L-shape steel is based on the cross-sectional area and length of the steel bar. The specific formula is as follows:

Mass (m) = Cross-sectional area (S) * Length (L) * Density of steel

Where:

• Cross-sectional area (S) is calculated by the formula provided in the previous information.
• Length (L) is the length of the steel bar, usually measured in meters.

You can use this formula to calculate the mass of L-shape steel based on its dimensions and length.
