Regular spangle GI steel coil with a requested Z120 coating class for HVAC ductwork, ventilation components and sheet-metal fabrication. Confirm DX51D or the required grade, thickness, width, surface, slit schedule, packing and quantity per order.
Bomis Steel’s Regular Spangle GI Steel Coil – Z120 HVAC Ductwork is a galvanized steel coil option for ventilation ducts, air-handling components and related sheet-metal parts. The brief requests a regular-spangle surface and Z120 coating class. Confirm the governing standard, grade, thickness, width, surface treatment and slit schedule before production.
The regular-spangle surface gives the coil a visible galvanized appearance. Z120 is the requested coating class for this brief; confirm the final coating requirement against the ductwork environment, forming route and project specification.
HVAC ductwork also depends on predictable forming. Bomis can review the grade, base-metal thickness, coil width, edge condition and cutting or slitting schedule before quotation. DX51D or another grade may be specified when the project requires a particular forming or standard condition.
Regular spangle is not a substitute for the purchase schedule. The visible finish, zinc-coating request and substrate grade should travel together in the enquiry. That gives the buyer a clearer comparison between offers and gives the factory a defined basis for checking production feasibility.

Use this galvanized coil when a ductwork or fabrication line needs a defined zinc-coating class and a regular-spangle surface. Send the duct section, joint method and finished dimensions with the enquiry so the steel grade and thickness can be checked before production. Include the downstream operation as well: folding, lock forming, roll forming or cut-to-length work can change the required width, edge and tolerance review. Bomis can confirm the final combination per order.
Confirm thickness, finished width, slit widths, tolerance, edge condition and forming method before ordering. State whether the coil will be cut to length, roll formed or folded. Bomis can review the Z120 request with the required standard, grade and surface treatment. See the galvanized steel coil range এবং buyer guide before sending the enquiry.
State the destination port, coil weight, inner diameter and orientation. Also confirm wrapping, strapping, edge protection and moisture protection before production. The final export packing method follows the handling plan and buyer specification. Marking and lifting points should be agreed when the shipment needs special handling.
No. Z120 is the requested class here, but confirm exposure, forming and project requirements before approval.
DX51D may suit a commercial forming route. State another required standard or grade in the enquiry.
Yes. Send finished widths, tolerance, edge requirement and quantity.
Choose the condition after reviewing storage, forming and downstream coating. Confirm it per order.
Send grade, standard, dimensions, Z120 request, surface, edge, quantity, packing and destination. Add a drawing when needed.
No. Coating class, substrate grade, dimensions and forming conditions also define the coil.
Yes. Include sheet dimensions, tolerance, quantity and packing, then confirm the processing route.
