Description
PGalvanized Profiled Sheet (Corrugated Sheet) is a steel profiled sheet with a protective zinc coating, widely used in construction due to the combination of strength, durability, and cost-effectiveness.
Production Technology
The manufacturing process includes the following stages:
1. Raw Material Preparation: Use of galvanized steel strip in coils.
2. Uncoiling and Straightening: Feeding material through an uncoiling device.
3. Profiling: Forming trapezoidal or wave profile on rolling mills.
4. Length Cutting: Cutting to specified sheet lengths with guillotine shears.
5. Stamping (optional): Applying additional stiffening ribs.
6. Packaging: Protective packaging of finished products.
Characteristics and Assortment
• Metal Thickness: 0.35-1.2 mm.
• Profile Height: 8-160 mm.
• Useful Width: 600-1250 mm.
• Sheet Length: 0.5-12 meters.
• Zinc Coating Thickness: 90-275 g/m².
• Steel Grades: 220-350, 250-420, 280-420.
Profile Types
• Wall (C): Low profile (8-44 mm).
• Load-bearing (H): High profile (57-160 mm).
• Universal (HC): Medium profile height.
Advantages
• High Corrosion Resistance.
• Low Weight with significant load-bearing capacity.
• Easy and Fast Installation.
• Durability (service life 25-50 years).
• Resistance to atmospheric influences.
• Cost-Effectiveness.
Areas of Application
• Roofing Works: covering roofs of industrial and civil buildings.
• Fencing Structures: fences, gates, construction site barriers.
• Wall Cladding: facade cladding, sandwich panels.
• Interfloor Floors: permanent formwork.
• Outbuildings: garages, sheds, warehouses.
• Temporary Structures: pavilions, retail outlets.
Normative Documentation (GOST Standards)
Main standards regulating the production of profiled sheets:
GOST 24045-2016 – "Bent steel trapezoidal sheets for construction. Technical specifications"
• Defines technical requirements for profiled sheets.
• Establishes classification and test methods.
• Regulates acceptance and marking rules.
GOST 14918-2020 – "Continuously hot-dip zinc-coated steel sheet and strip"
• Defines requirements for the initial galvanized sheet.
• Establishes zinc coating classes.
GOST 30246-2022 – "Steel products with metallic coatings for construction"
• Regulates requirements for steel products with coatings.
Additional Normative Documents
• SP 17.13330.2017 – Roofs.
• SP 16.13330.2017 – Steel structures.
• GOST 19904-2015 – Cold-rolled steel sheet.
Quality Requirements
• Profile Geometry: compliance with specified parameters.
• Edge Quality: absence of burrs and deformations.
• Zinc Coating: uniformity, absence of uncoated areas.
• Surface: absence of scratches, dents, peeling.
