1.What are the core features and application scenarios of the bite wave type (locking edge wave type)?
Core Features
Structural Design: The corrugated edges feature built-in "mechanical interlocking grooves," eliminating the need for bolts to penetrate the panels during installation. Instead, specialized equipment securely locks the grooves of adjacent panels together (creating a "seamless connection"). The wave height is typically 15-35mm, and the wave spacing is 150-250mm.
Functional Advantages: Compared to conventional lap joints, this design offers over 80% improved sealing (completely preventing rainwater from seeping through the lap joints). It also boasts superior wind-up resistance (the locked-edge structure can withstand the negative pressure of typhoons above force 12). The panels also have no bolt holes on the surface, reducing the risk of corrosion.
Typical Applications
Harsh Climates: Factory/Warehouse Roofs in Coastal Areas Prone to Typhoons and Heavy Rainfall in Southern China.
Applications with High Sealing Requirements: Grain Storage Warehouses (to prevent rainwater and mold), Chemical Raw Material Storage Sheds (to prevent dust and moisture intrusion), and Cleanroom Exterior Walls (to reduce external contamination infiltration).
2.What are the characteristics and application scenarios of the reinforcing rib wave shape?
Core Features
Structural Design: Additional longitudinal reinforcement ribs (narrow raised strips running the length of the sheet, 5-10mm in height) are added between the regular corrugations (main waves), or transverse indentations are pressed into the top of the corrugations. The wave height is 15-30mm, and the wave spacing is 180-250mm.
Functional Advantages: The reinforcement ribs distribute the load, increasing the bending and flexural strength by 50%-100% compared to ordinary corrugated sheeting, preventing the sheet from bending or collapsing under loads such as snow accumulation or heavy equipment.
Typical Applications
High-load applications: Roofs in northern snowy areas (to support the weight of accumulated snow and prevent collapse), and industrial buildings with ventilation fans or solar panels on the roof.
Long-span structures: Large-span warehouses without intermediate supports (such as logistics sheds with spans over 15 meters), and rain shields for heavy equipment outdoors (to withstand minor vibrations and external impacts).
3.What are the characteristics and application scenarios of low-wave density wave types?
Core Features
Structural Design: Extremely low corrugation height (only 3-8mm), small corrugation pitch (30-60mm), dense and gentle corrugations, resulting in an overall flatness close to that of a flat plate with no noticeable surface protrusions.
Functional Advantages: The smooth surface allows for direct painting or decorative film application without additional treatment, and is highly resistant to dust accumulation after installation. The low corrugation height makes it suitable for confined spaces or applications requiring "invisible" installation, eliminating the need for additional height.
Typical Applications
Decorative Applications: Factory exterior wall panels (a lower-cost alternative to traditional tiles/paints), temporary building interior partitions (such as office partitions on construction sites);
Protective Applications: Equipment protective shields (such as chip guards for machine tools in workshops), elevator shaft guards (for safety in small spaces).
4.What are the characteristics and application scenarios of anti-corrosion reinforced wave type?
Core Features
Structural Design: In addition to the conventional galvanized coating, the sheet is additionally treated with a "double-layer galvanizing" (the zinc layer thickness reaches over 275g/㎡, far exceeding the 120g/㎡ of ordinary galvanized sheet), or an anti-corrosion coating (such as PVDF fluorocarbon coating or polyester coating) is sprayed onto the corrugated surface. The corrugation pattern is typically trapezoidal or interlocking (balancing load-bearing and sealing), with a wave height of 15-30mm.
Functional Advantages: Extremely corrosion-resistant, resistant to acid, alkali, and salt spray (such as high salt spray at seaside locations and corrosive gases in chemical plants), with a service life 2-3 times longer than that of ordinary galvanized corrugated sheet (5-8 years for ordinary sheet, 15-20 years for anti-corrosion).
Typical Applications
Highly corrosive environments: Coastal dock warehouses, saltworks buildings, and chemical plant exterior walls/roofs.
Long-term outdoor use: Rain shelters for open-air garbage disposal stations, covers for sewage treatment plants, and corrosion-resistant fencing in agricultural aquaculture areas (such as around seawater aquaculture ponds).
5.What is the selection logic for special functional types?
The core of special-purpose cladding is "scenario adaptability." When choosing, prioritize your core requirements:
For leakproof and windproof cladding, choose the snap-fit corrugated cladding;
For load-bearing and snow-resistant cladding, choose the reinforced corrugated cladding;
For decorative purposes or installation in small spaces, choose the low-density corrugated cladding;
For acid and alkali resistance and corrosion resistance, choose the anti-corrosion reinforced corrugated cladding.
