Product Description

Randall Manufacturing - Corrugated Aluminum Thresholds

6063 alloy aluminum

Made From 6063 Alloy Aluminum with T-6 Temper

6063 Alloy Properties

Corrosion resistance - 6063 aluminum is highly resistant to corrosion, especially when given an appropriate surface finish. This makes it a good choice for applications where it may be exposed to water or weather.

Strength - 6063 aluminum has ample strength and stiffness, making it a great choice alloy for building applications such as door thresholds.

Surface finish - 6063 aluminum has a much smoother surface finish than other commercially available alloys, making it a good choice when visual appeal is important.

T-6 Temper Properties

Strength - T-6 aluminum has high tensile and yield strength, respectively. This can be higher than the yield strength of some types of stainless steel. Making it perfect for applications that will get a lot of stress - such as a threshold that will have heavy object going over it.
