Frequently Asked Questions
Yes, all our steel calculators and reference charts are 100% free. No registration, no hidden fees. We provide these tools as a service to the global steel trading community. Bookmark this page for quick access anytime.
Our calculators use standard industry formulas and material densities (e.g., 7.85 g/cm³ for carbon steel). The theoretical weight calculated is typically within 1-3% of actual weight. Minor variations occur due to manufacturing tolerances, coating thickness, and edge trimming. For commercial transactions, always weigh coils on a certified scale.
We supply galvanized steel coils (GI), pre-painted galvanized steel (PPGI/PPGL), galvalume coils (GL), cold rolled coils (CRC), hot rolled coils (HRC), tinplate, and color-coated steel products. We export to 150+ countries with competitive FOB China pricing. Contact us for a detailed product catalog and current price list.
Yes! All our tools are fully responsive and work on smartphones, tablets, and desktop computers. You can use them in the field, at the warehouse, or in your office. No app download needed — just open in your browser.
Container loading estimates are based on standard payload limits: 20ft GP (~25 tons), 40ft GP (~26 tons), 40ft HQ (~27.5 tons). The actual number of coils per container also depends on coil outer diameter, inner diameter, and stacking method (eye-to-sky vs eye-to-side). For precise loading plans, please consult with our logistics team.
