Inside the China 14 ft Metal Roofing Price Factory Scene: What Buyers Really Pay For

If you’re mapping out costs for long-span panels, you’ll inevitably stumble upon china 14 ft metal roofing price factory discussions. And yes, I’ve walked a few lines in Hebei and Shandong where the numbers are set, re-set, and negotiated. Prices shift with zinc futures, coil width, and—surprisingly often—cut-to-length waste. In other words, the headline per-kg cost is only half the story.

Product at the core: Price Electro Galvanized Iron Per KG (EGI Steel)

The workhorse material many 14 ft roofing lines rely on is EGI—electro-galvanized iron/steel. XD’s line out of Shijiazhuang (Room 1017, Qicheng Building, No.210, ZhongHuanan Street, Qiaoxi District, Hebei) feeds coils that are then roll-formed into panels or trims. EGI is clean, consistent, and easy to paint; for coastal roofs, some buyers step up to heavier zinc or AL-Zn, but EGI wins on formability and finish quality.

How price is really set

• Materials: cold-rolled base + electro-zinc bath, passivation, oiling or dry finish.
• Methods: line speed ≈30–120 m/min; edge trimming; roll forming for 14 ft lengths.
• Testing: coating weight (magnetic gauge), adhesion (T-bend), salt spray (ASTM B117, 240–480 h typical), thickness mic.
• Yield calculus: coil width vs. panel profile determines scrap; 14 ft panels add cut-loss.
• Logistics: Hebei to port + container111 rates; honestly, freight can swing your landed cost by 5–12%.

Service life? In moderate inland climates, coated EGI roofing with a decent paint system runs ≈15–25 years; coastal, more like 8–15 unless you spec heavier coating or move to Al-Zn. Many customers say the sweet spot is upping paint quality rather than only chasing coating grams.

Applications and customization

Use-cases: commercial sheds, container111ized shelters, marine-grade trims, residential roofs, and wall cladding. Custom options: coil width, target 14 ft lengths, paint system (PE, SMP, PVDF), embossing, anti-fingerprint. For china 14 ft metal roofing price factory quotes, ask for profile drawings and net cover width; that’s where your yield lives.

Case notes from the field

A logistics park in Tianjin switched to EGI + SMP topcoat, 0.4 mm, and reported fewer oil-canning complaints—probably the tighter gauge and better roll-form dies. Another coastal repair job tried heavier coating; still, the win came from sealant detailing and end-lap design. To be honest, profile geometry and install practice can save more money than shaving $20/ton from a china 14 ft metal roofing price factory deal.

Testing and compliance checklist

• Coating mass: JIS G 3313 / GB/T 2518.
• Salt spray: ASTM B117 (specify hours, e.g., 240 h baseline).
• Adhesion and bend: T-bend, impact per factory QMS.
• Quality system: ISO 9001 certificate match to plant address.
