ERW Pipe Description
ERW steel pipes are manufactured by low-frequency or high-frequency resistance “resistance”. They are round pipes welded from steel plates with longitudinal welds. It is used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure. At present, it occupies a pivotal position in the field of transportation pipes in the world.
During ERW pipe welding, heat is generated when current flows through the contact surface of the welding area. It heats the two edges of the steel to the point where one edge can form a bond. At the same time, under the action of the combined pressure, the edges of the tube blank melt and squeeze together.
Typically the maximum outside diameter of ERW tubing is 24″, and as a specialty manufacturer, baolai can go up to 26″.

FAQ
1. What types of highway guardrails does Baolai supply?
▼
Baolai supplies W-beam and Thrie-beam guardrail components for road and infrastructure projects. Available components may include beams, posts, blockouts, fasteners, terminals, transitions, and related accessories. The final component set must match the approved guardrail system, project drawings, and local road authority requirements.
2. What components are included in a highway guardrail system?
▼
A system may include corrugated beams, posts, blockouts or spacers, splice bolts, post fasteners, terminal sections, transitions, reflectors, and other accessories. The exact combination varies by system and performance requirement. Terminals, transitions, post spacing, and fasteners should not be changed independently because they affect the behavior of the complete roadside restraint system.
3. How should buyers choose between W-beam and Thrie-beam guardrails?
▼
Choose the complete system according to the required containment or test level, working width, dynamic deflection, impact severity, roadside geometry, traffic conditions, post spacing, terminal details, and approved drawings. The beam profile alone does not determine crash performance. Buyers should provide the authority-approved system specification rather than selecting W-beam or Thrie-beam only by road type.
4. Can highway guardrail components be customized for project standards?
▼
Baolai can manufacture components to specified material, dimensional, hole-layout, coating, and drawing requirements, subject to technical review. Where a crash-performance standard applies, the supplied configuration should match the approved or tested system documentation. Component substitutions should be reviewed by the project engineer or road authority.
5. What details are needed for a guardrail quotation?
▼
Provide the approved system drawings or bill of materials, guardrail profile and total length, beam thickness and effective length, post type and spacing, blockout type, terminal and transition requirements, fastener schedule, galvanizing or coating specification, applicable standard, inspection documents, destination port, and delivery terms.
