Gi Plain Sheet Dimensions
- The commonly used thickness of Gi plain sheet is 0.2mm, 0.4mm, 0.45mm, 0.5mm, 0.6mm, 1.5mm, etc.
- The common width is 600mm, 1000mm, 1219mm (4 feet), 1250mm, 1500mm, etc.
- The length of Gi plain sheet can be extended according to your requirements.
What does 4×8 Gi Plain Sheet mean?
4×8 stands for 4 feet * 8 feet, which is converted to mm and refers to a gi plain sheet with a width of 1219.2mm and a length of 2438.4mm.Galvanized steel sheets of this specification of 1219mm×2438mm are easier to arrange during production and transportation, so they are more common.
Gi Plain Sheet Weight Calculator
Weight per square meter (kg) = thickness (mm) × length (m) × width (m) × 7.85 (Gi sheet density)
For example, the weight (kg) of a galvanized steel sheet with a thickness of 0.5mm, a width of 1000mm, and a length of 2100mm = 0.5×1×2.1×7.85=8.2425kg; For quick calculations, utilize our metal sheet calculator to obtain results rapidly.

Advantages of GI Plain Sheet
- Ready-to-Use: Supplied as pre-processed flat sheets, eliminating the need for pre-treatment steps like coil unwinding, slitting, and cross-cutting.
- Superior Surface Quality: As a flat sheet, it offers high flatness, consistent surface finish, and is free from roller marks or zinc particles.
- Enhanced Processing Stability: The galvanized flat sheet exhibits a more stable internal stress state, resulting in minimal deformation during subsequent processing and high precision in finished products.


Gi Plain Sheet Applications
- Electrical Enclosures: Used for manufacturing high/low-voltage switchgear, distribution boxes, server cabinets, and network cabinet housings, door panels, and mounting plates.
- Building Structures: Serves as backing panels for metal curtain walls, ceiling base panels, interior partition wall panels, and industrial stair treads (embossed).
- Transportation Facilities: Interior trim panels for subways/high-speed rail/buses, highway sound barrier panels, and traffic sign backing panels.
- Industrial Equipment: Agricultural machinery housings, agricultural buildings, ventilation ducts, fan enclosures, environmental protection equipment casings, etc.
