Red Polyester Aluminum Trim Coil for Exterior Building Trim

Red Polyester Aluminum Trim Coil for Exterior Building Trim

Red aluminum trim coil is prepainted aluminum coil stock designed for fabrication into exterior building trim, fascia covers, window and door wrapping, roof flashing and other formed architectural details. This product uses a durable aluminum substrate with a red polyester-coated finish for applications requiring a consistent decorative appearance and practical outdoor performance.

The current red trim coil specification is based on nominal 0.019-inch aluminum, AA3105 alloy and H28 temper. The material can be cut and brake-formed into custom profiles according to project dimensions, installation details and contractor requirements.

Dingang supplies aluminum trim coil for contractors, building-material distributors, fabricators and exterior finishing projects. Additional widths, colors, alloys and coating systems can be discussed for project and wholesale orders.

Red Aluminum Trim Coil Product Specifications

Available Aluminum Trim Coil Specifications

The following specification chart shows available aluminum trim coil configurations within the product range. It includes options that may differ from the standard red AA3105-H28 polyester-coated configuration above. Please confirm the required alloy, temper, width and coating system before production.

Why Choose Red Polyester Aluminum Trim Coil?

Distinctive Red Exterior Finish

Red trim coil provides a strong architectural accent for exterior building details. It can be used to coordinate fascia, window surrounds, roof edges and other formed components with siding, roofing or branding colors.

Factory-Applied Polyester Coating

The polyester coating is applied before fabrication, providing a uniform finished surface and reducing the need for secondary painting after the trim profile has been formed.

Formable AA3105 Aluminum

AA3105 aluminum is widely used for painted building products and formed exterior components. The selected thickness and temper provide a practical material for suitable brake-forming and trim fabrication operations.

Lightweight and Corrosion Resistant

Aluminum is lightweight and does not rust in the same way as ordinary carbon steel. These characteristics make coated aluminum practical for exterior trim applications where handling, appearance and corrosion resistance are important.

Suitable for Custom-Formed Profiles

Trim coil can be cut and bent into different profiles according to project requirements. Contractors and fabricators can form fascia covers, window wraps, flashing, edge details and other custom exterior components using appropriate sheet-metal equipment.

Typical Applications

Fascia Board Covers

Red aluminum trim coil can be formed into fascia covers to provide a finished metal surface around roof edges and coordinate fascia color with other exterior building components.

Window and Door Trim

The coil can be brake-formed into window and door surrounds, capping profiles and edge details for residential and commercial exterior finishing projects.

Roof Flashing and Edge Trim

Where suitable for the building design, aluminum trim coil can be formed into flashing, drip-edge-type profiles and other roof-edge details. Final dimensions and installation methods should follow project requirements.

Exterior Wood Wrapping

The material can be formed to cover exposed exterior wood trim, creating a finished aluminum surface while reducing direct exposure of the underlying material to the weather.

Architectural Accent Trim

Red trim coil can also be used for decorative edge covers, accent bands and other formed exterior details where a strong red color is part of the architectural design.

Discuss Your Red Trim Coil Application

Designed for Cutting and Brake Forming

Aluminum trim coil is commonly fabricated with a sheet-metal brake to create custom profiles directly from flat coil stock. The required flat width should be calculated from the finished profile dimensions, including bends, hems, overlaps and fastening areas.

Appropriate tooling, bending radius and handling procedures should be used to minimize marking or excessive stress on the prepainted surface. Protective handling is particularly important on visible architectural components.

For production projects, buyers can provide a drawing or finished profile dimensions so that suitable coil width and material specifications can be reviewed before ordering.

Red Color Matching and Project Orders

Red is available in different shades depending on the coating system and project requirement. For exterior projects that must match existing siding, roofing, cladding or corporate colors, buyers should provide an agreed color reference or physical sample.

For repeat orders, distributors and fabricators should identify the previously approved color specification to improve consistency between production batches. Color tolerance, gloss level and coating type should be agreed before mass production.

How to Select Aluminum Trim Coil

1. Confirm the Required Color

For red projects, provide a color reference or approved sample when exact matching is important. Different red shades can produce visibly different results on a finished elevation.

2. Confirm the Required Thickness

The standard product description uses nominal 0.019-inch aluminum. If a different thickness is required for stiffness or forming performance, specify it when requesting a quotation.

3. Calculate the Required Coil Width

Calculate the developed width of the finished profile, including all folds, hems and overlaps. Selecting a suitable coil width can reduce cutting operations and material waste.

4. Confirm Alloy and Temper

The red product description specifies AA3105-H28. Other trim coil configurations may use different alloys and tempers, so the final combination should be confirmed according to forming requirements.

5. Select the Appropriate Coating System

This red product is described with a polyester finish. Other coating systems can be discussed for projects with different exterior exposure, color-retention or specification requirements.

6. Confirm the Fabrication Method

Tell us whether the material will be brake-formed, roll-formed, slit or fabricated into a specific profile. This information helps review thickness, temper and width requirements.

Information to Provide for a Quotation

For a faster and more accurate quotation, please provide:

• Required red color or approved color reference

• Aluminum alloy

• Temper

• Thickness

• Coil width

• Coating requirement

• Required quantity

• Finished application or profile
