Perforated aluminum has a strong resistance to corrosion due to an oxide skin formed in reaction with the atmosphere. It is a relatively light metal compared to metals such as steel, nickel, brass, and copper and is rather malleable. It can have a wide variety of surface finishes and is highly reflective to heat and light. For most applications, aluminum sheets need no protective coating but are often anodized to improve color and strength.

Perforated sheet aluminum is extremely useful at low-temperatures. At subzero temperatures its strength increases while retaining ductility. At temperatures over 400F aluminum alloy sheets tend to lose some of their strength.

We produce perforated aluminum with the finished product either in sheet or coil form depending on customer requirements. Our high quality perforated aluminum is complimented by many additional capabilities including precision shearing, degreasing, deburring, bending, and rolling. We take great pride in our ability to perforate a large range of material sizes and gauges

Once these perforated aluminum products leave our facility, they are used in a broad range of industries. Some examples of typical aluminum uses are various decorative and aesthetic applications, filtration of both air and liquids, interior and exterior architectural accents, and a multitude of internal oem parts for everyday end-user products

If you can envision it,We can supply it. TEL:0086-318-7979121 E-mail:sales@steellong.cn MSN：Service@Steellong.Cn

Aluminum combines a unique set of properties (lightweight and resistant to corrosion). It is also nontoxic which makes it an excellent material in cooking utensils. Most aluminum types are an alloy of aluminum, which includes a small quantity of silicon, iron, copper, magnesium, or nickel. These alloys differ in hardness, tensile strength, and other properties.

Non-Heat Treatable (Common) Alloys

1100-0 - Commercially pure aluminum. Excellent corrosion resistance, workability and weldability; high thermal conductivity. Uses include deep drawing, spinning, sheet metal work, decorative applications, air ducts, etc.

3003-0-H14 - The most widely used general purpose alloy. 3003 is stronger than 1100 but still readily formable. Excellent resistance to chemicals and weathering.

5005-H32 or H34 - Excellent workability, weldability, and corrosion resistance. 5005 is typically specified for applications where anodizing is required. Anodized coating is clear and lighter than 3003.

5052-H34 - A versatile alloy for applications requiring greater strength. Readily formed, very good corrosion resistance in marine applications.

Heat Treatable (Strong) Alloys

6061-T4 or T6 - High strength allow provides good formability, weldability, and corrosion resistance. May be difficult to perforate or bend.

6063-T6 - Highly corrosion resistant with good formability. Softer than 6061-T6 and easier to bend. Finish is pleasing and is the most suitable for anodizing.

Aluminum Insect Screen

Bright - This finish is a light gray, bright finish. Screening in this color is more visible than the charcoal color, especially when viewed from the side with the most light (for example, from the outside looking into a screen porch).
