Bright Round Bars

Bright finish refers to a cold-drawn or cold-rolled surface that achieves a smooth, reflective appearance through mechanical processing without additional polishing. It typically has a surface roughness (Ra) of 0.2-0.4 μm. Polished finish involves additional buffing or grinding processes to achieve specific surface textures, which can range from directional polishing to mirror polishing with even lower Ra values. Bright finish is our standard offering and is ideal for most applications, while polished finish is customizable based on specific aesthetic or functional requirements.

Our Bright Round Bars are manufactured to very tight dimensional tolerances. For smaller diameters (3-10mm), we achieve ±0.02mm tolerance. Medium sizes (10-20mm) maintain ±0.03mm, while larger diameters have proportionally adjusted tolerances up to ±0.15mm for the largest sizes (200-300mm). For applications requiring even tighter tolerances, we offer centerless ground bars with precision tolerances as tight as ±0.01mm. Straightness is maintained at 0.5mm per meter maximum deviation, and surface roughness is consistently kept at Ra 0.2-0.4 μm.

Yes, we offer both standard and custom length options. Our standard lengths are 3m, 4m, 5m, and 6m. For custom requirements, we can provide precision cutting to any length from a minimum of 500mm up to 6 meters. All custom cuts are made with ±1mm tolerance and include deburred and chamfered ends as standard. For lengths exceeding 6 meters, special arrangements can be made depending on the diameter and quantity required. Custom cutting services are available with minimal additional lead time for most orders.

Lead times vary based on product specifications and order quantity. For stock items in common grades (304, 316) and standard sizes, we typically ship within 3-5 business days. Standard orders for in-production items require 7-14 days. Custom specifications including non-standard sizes, special finishes, or less common grades typically need 21-30 days. Large volume orders (>20 tons) are scheduled based on production capacity and may require 4-6 weeks. We maintain extensive inventory of popular sizes to ensure quick turnaround for urgent requirements. Expedited processing is available for critical orders.

Yes, we provide comprehensive material test certificates (MTC) with every order as standard practice. Our certificates comply with EN 10204 3.1 standards and include complete chemical composition analysis, mechanical property test results, heat number traceability, dimensional verification data, and surface finish confirmation. For applications requiring third-party verification, we can arrange EN 10204 3.2 certificates at a nominal additional cost. All certificates are digitally signed and can be provided in both physical and electronic formats. We also maintain complete traceability records for all materials for a minimum of 10 years.

Minimum order quantities (MOQ) are established based on diameter ranges to ensure economical production and shipping. For small diameters (3-20mm), the MOQ is 100 kg. Medium diameters (20-100mm) require a minimum of 250 kg, while larger diameters (100-300mm) have an MOQ of 500 kg. For mixed orders containing multiple sizes or grades, we can accommodate lower quantities per item as long as the total order meets the overall minimum of 250 kg. Sample quantities (typically 5-10 pieces) are available for evaluation purposes at standard pricing plus shipping costs.

Absolutely. We encourage consolidated orders containing multiple grades, sizes, and finishes as it optimizes shipping costs and simplifies logistics. Each grade and size will be clearly identified with color-coded tags and comprehensive labeling including grade , heat number, size, and order reference. We maintain strict segregation during processing and packaging to prevent any cross-contamination between grades. All items in a consolidated order ship together unless otherwise requested. Mixed orders receive a comprehensive packing list detailing all components, and individual MTCs are provided for each grade and heat lot. This flexibility allows you to optimize your inventory while maintaining quality assurance for each component.

We offer comprehensive packaging solutions designed to protect your material during transit. Standard packaging includes hexagonal bundling with steel strapping, plastic end caps, and waterproof wrapping. Each bundle is labeled with grade, size, heat number, and order details. For export shipments, we provide wooden crates or palletization as required by destination country regulations, complete with fumigation certificates when necessary. Special packaging for sensitive applications includes individual protective sleeves, segregated compartments, and custom crating. All packaging complies with international shipping standards and can be customized based on your specific handling and storage requirements.
