Quality trim sheets add the finishing touch to any home's exterior, and Alcoa's trim sheet is the highest quality available in a wide range of colors to complement virtually any home's exterior, our trim sheets 'long-lasting finishes stand up to the toughest conditions nature offers. What's more, the strength, durability and consistency of the aluminum itself meet the industry's most demanding standards.

Alcoa Performance Metals – The Right Foundation
Quality trim sheets begin with quality materials. Alcoa manufacturers use aluminum that meets our "Q801" standards – demanding specifications that cover a wide range of properties, including characteristics many manufacturers ignore:

  • Tensile strength­ - the underlying strength of the aluminum itself.
  • Elongation and yield strength - important requirements that affect how well the trim sheet can be shaped and formed in the field.
  • Metal grain requirements­ – a key factor that ensures the trim can be bent and shaped as desired, without causing the finish to crack or split.
  • Corrosion-resistance - of utmost importance in ensuring the long life of the exterior finish.
  • Flatness - an essential factor in providing a smooth, buckle-free finish.

You can count on long runs of material without ripples, waves or "oil canning". Our trim sheets bend and form beautifully, with craze-free corners and burr-free edges ­the tight foundation for a quality finish.

Quality you can afford
Surprisingly, you don't have to pay more for the best. Alcoa trim sheets offer exceptional quality that other manufacturers' products cannot. Considering waste reduction, most contractors use Alcoa trim sheets at a comparable cost to products of lesser quality.

To enhance any exterior
Enhancing a home's curb appeal is easy with the right combination of colors. Alcoa's wide selection of colors coordinates with almost any architectural style and color scheme - giving you the freedom to create the best look for your home.

Time tested performance
Alcoa trim sheets must conform to rigid corrosion­ resistance specifications, and undergo constant testing and quality control. The aluminum's metal chemistry and casting technology are closely screened and monitored, while the finishes have undergone years of testing, both in laboratory simulations and at independent outdoor weather stations. With their long life and durable good looks, our trim sheets stand up to nature's toughest challenges.
