Product selection and use guide
Lokfom BJLS Large Galvanized Steel Coil is galvanised steel BJLS stock for fabrication in sheet or roll form. Coil or roll form is fabrication stock that must be uncoiled and cut.
How to choose
Match base thickness, dimensions, required coating and bending patterns for ducts or cladding. Check coil width, thickness and cutting equipment capacity before defining working lengths.
Applications to consider
Consider duct fabrication, covers or metal details specified in the drawings.
Use limitations
BJLS is not insulation infill and galvanising does not eliminate all corrosion risks. Cut edges, moisture and joint details still matter.
Pre-order checklist
- Send thickness, sheet dimensions or roll width and ordering units.
- Include bending patterns, joints and any coating requirements.
- Confirm ordering units, required weight or length and coil handling facilities.
Frequently asked questions
Are BJLS roll and sheet ordered the same way?
Not always. Confirm units, width, cut lengths or required weight.
Does BJLS plate already insulate a duct?
No. The plate forms the duct body; insulation is a separate component.
Does a brand name guarantee a particular thickness?
No. Select an explicit variant and size and confirm its tolerances.
Is coil ordered like sheet?
Confirm the units. Length, weight and cut-piece sizes must not be treated as identical.
