PRODUCT DESCRIPTION
Electric resistance welded (ERW) steel pipe offers exceptional versatility and durability, making it suitable for various industrial and structural applications. Manufactured with precision, ERW steel pipes are available in different grades such as A500 Grade B, A513, and A135, ensuring compatibility with diverse project requirements.
These pipes feature a semi-smooth, non-coated dark grey surface finish and a welded seam on the interior, providing a robust and consistent structure. Renowned for their high performance, ERW steel pipes are commonly utilized in applications such as railings, exhaust systems, roll cages, hinges, and other mechanical and structural uses.
The A500 Grade B standard specifies requirements for cold-formed welded and seamless carbon steel structural tubing, designed for strength and reliability in construction and infrastructure projects. The A513 standard ensures high-quality electric-resistance-welded carbon and alloy steel mechanical tubing, ideal for demanding mechanical applications. The A135 standard focuses on electric-resistance-welded steel pipes for high-efficiency applications.
With its combination of strength, durability, and adaptability, ERW steel pipe is an optimal choice for engineers, manufacturers, and construction professionals.
