YS STEEL provides one-stop services, including size customization, cutting, stamping, and anti-corrosion treatment. It also has an adequate inventory to support large-scale procurement needs for global engineering projects.
The Hot Rolled I Beam Steel is rolled from refined steel billet under controlled temperature, giving a uniform metallographic structure free of bubbles, cracks and inclusions. Flange flatness and web straightness meet GB/T 706, EN 10034 and ASTM A6/A6M limits. Tensile strength, yield strength and elongation are tested batch by batch and meet the standard before shipment. Under long-term static load, the beam shows no measurable deformation.
High-purity raw material with low impurity content gives the beam basic resistance to rust and oxidation in outdoor, humid and low-temperature conditions. Surface treatment is selected by environment: rust-proof painting for indoor dry conditions; hot-dip galvanizing or thickened anti-corrosion coating for outdoor exposure, high humidity and acid/alkali environments. Coating thickness and process are specified per project, extending service life and reducing replacement frequency.
Chinese standard 10#–63# and the complete European IPN / IPE series are held in stock. Light to heavy-duty models are available for direct shipment. Cutting, punching, bending and welding are performed to client drawings for non-standard lengths and joint details, covering both standard and non-standard engineering requirements.
The I-shaped cross-section places material where bending stress is highest, distributing stress evenly along the web and flanges. Under equivalent load, the I beam uses less steel than ordinary section steel, reducing structural self-weight and foundation load. This lowers total material cost on large-span and high-load projects.
Each batch ships with material certificates, mechanical test reports and factory qualification certificates. SGS, BV and other third-party inspections are supported. Export documents comply with the import and engineering acceptance requirements of the destination market, allowing direct use in cross-border projects without additional verification steps.

• Southeast Asia Industrial Factory Steel Structure Project (2025): We supplied over 800 tons of Q355B Chinese standard 20#-40# hot-rolled I beams for factory expansion projects of multiple industrial parks in Vietnam and Cambodia. The products were applied to main factory frames, roof load-bearing structures and equipment bases. We provided integrated services including fixed-length cutting and galvanized anti-corrosion processing, delivered all goods on schedule, and passed local engineering quality inspection, helping clients complete factory completion and operation and obtain long-term strategic cooperation qualification.
• Middle East Municipal Bridge Infrastructure Project (2025): We undertook the municipal bridge renovation project in Saudi Arabia, supplying 520 tons of S355JR European standard IPE series I beams. Customized thickened anti-corrosion coating was adopted to adapt to local high temperature, sandstorm and high-corrosion environments, ensuring product weather resistance and structural stability. Applied to bridge auxiliary load-bearing structures and guardrail frames, all products passed local authoritative engineering inspection, winning high recognition for delivery quality and service efficiency.
• Domestic Large-Scale Warehousing & Logistics Base Project (2024): We provided 460 tons of Q235B series I beams for a large intelligent warehousing base in East China, applied to high-level storage rack support structures and building frames. With precise dimensional accuracy and stable load-bearing performance, the products fully met the high-load and high-stability construction requirements of high-level warehousing, achieving zero quality defects in delivery and becoming the long-term fixed profile supplier of the client.
Cutting: Flame cutting, plasma cutting and band sawing are all suitable. For flame-cut edges on thick sections, grind the cut face to remove the heat-affected zone before welding.
Welding: For Q235B, standard E43 series electrodes are suitable. For Q355B, use E50 series electrodes. Preheating at 100–150°C is recommended for flange thickness above 20mm or when the ambient temperature is below 0°C.
Bolt Holes: Punching is suitable for web thickness up to 12mm. For thicker webs or high-precision connections, drilling is recommended to avoid edge cracking.
Storage: Stack on timber or steel dunnage at least 100mm above ground, with adequate ventilation between layers to prevent condensation. Avoid direct ground contact and standing water.
| Environment | Recommended Treatment | Inspection Cycle | Maintenance Action |
| Indoor dry (warehouse, factory) | Anti-rust primer | Every 3–5 years | Touch up scratches; repaint if rust spots appear |
| Outdoor exposed (inland) | Anti-rust primer + topcoat | Every 2–3 years | Check coating adhesion; repaint damaged areas |
| High humidity / rainy | Hot-dip galvanizing (≥60μm) | Every 2 years | Inspect for white rust; clean and touch up as needed |
| Coastal salt spray | Hot-dip galvanizing (≥85μm) + topcoat | Every 1–2 years | Inspect coating thickness; repair any mechanical damage immediately |
| Acid / alkali / chemical | Thickened epoxy coating or galvanizing + epoxy | Every year | Check for coating blistering or peeling; re-coat exposed areas |
White rust on galvanized surface: Caused by moisture trapped between stacked beams during transport or storage. Remove with a nylon brush and apply a zinc-rich touch-up coating. Prevent by ensuring ventilation during storage.
Rust at cut edges or weld zones: The coating is damaged at these points. Clean to bare metal, apply zinc-rich primer, then topcoat.
Minor flange deformation after transport: Cold straightening is not recommended for load-bearing members. Contact us for assessment before any corrective action.
Weld cracking at flange-web junction: Usually caused by insufficient preheating or excessive restraint. Refer to our welding parameter recommendations before rework.
Indoor dry environment with anti-rust primer: 15+ years
Outdoor inland with primer + topcoat: 10–15 years
Hot-dip galvanized, general outdoor: 15–25 years
Hot-dip galvanized, coastal salt spray: 10–20 years
These figures assume normal maintenance and no mechanical damage to the coating.
