Product selection and use guide
Fumira BJLS Galvanized Steel Sheet is galvanised steel BJLS stock for fabrication in sheet or roll form. Sheet form provides flat stock for fabrication.
How to choose
Match base thickness, dimensions, required coating and bending patterns for ducts or cladding. Match sheet length and width to bending patterns and joint allowances.
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.
- Include cutting patterns, metal thickness and dimensional tolerances.
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.
Does sheet area equal installed coverage?
Not always. Folds, overlaps and cut-outs can reduce effective coverage.
