Metal Ventilation Duct, fom which aspects should we make improvements so as to create the best ventilation ducts in China?
- Raw material selection: Low cost and corrosion resistance, suitable for general ventilation systems (such as shopping malls and office buildings);
- Key points of processing technology: Use laser cutting or CNC plasma cutting to ensure the cut is smooth and free of burrs;The bending machine needs to control the R Angle curvature (if it is too small, it will cause the airflow vortex).
- Structural strength and support: For large-sized pipes (side length >800mm), transverse/longitudinal reinforcing ribs (spacing ≤1.5m) need to be installed.
- Anti-corrosion and surface treatment: The cutting surface should be sprayed with a zinc-chromium coating (such as cold galvanized paint) to prevent rusting of the cut;
- Connection and Installation:The flange gasket is made of oil-resistant rubber (for petroleum environments) or chloroprene rubber;

FAQ
Q:Why are air vents metal?
A:They are durable, puncture-resistant, and less prone to leaks.
Q:Is aluminium ducting better than plastic?
A:Aluminum ducting excels in terms of durability, fire resistance, and thermal conductivity, while plastic ducting offers cost-effectiveness and ease of installation.
Q:What is an electrical junction box used for?
A:They house and protect electrical connections at vulnerable points.
Q:What is the rule for bending aluminum?
A:The bend radius for aluminum should be 3-5 times the thickness of the metal.
Q:What are the three types of bending?
A:Air Bending, Bottoming and Coining
Q:What is the standard for sheet bending?
A:Place holes away from bends at a distance of at least 2.5 times the material's thickness (T) plus the bend radius (R).
Q:What is the maximum thickness of sheet metal bending?
A:The thickest bendable aluminum is 3/16" or 0.187"(4.75mm).
Q:Which aluminum is best for bending?
A: Aluminum Alloy 3003.
Q: What information does an inquiry require?
A: In order to accurately evaluate the cost, you need to provide drawings or samples, and propose specific requirements for materials, surface treatment, etc. In addition, the quantity required is also very important, as we will use different processing techniques for different quantities.
