Aluminum Corner Trim 8' - Pack of 4
Once you've set up the polycarbonate wall panels for your greenhouse, you need a way to properly secure them. This 8-foot aluminum outside corner trim makes the building structurally sound while forming a weather-tight seal. Our 90-degree metal corner trim is lightweight, rustproof and corrosion-resistant. The offset grooves make it easy to abut panels at the corner while covering the joint on both the exterior and interior, improving insulation and safety.

They're an excellent way to finish panels for greenhouses as well as enclosed patios, sheds and other structures. We sell aluminum corners for siding in packs of four - one for each building corner. Create a custom polycarbonate greenhouse using durable aluminum corner trim that qualifies for free shipping in the lower 48 states.
Purchased several pieces to use as a ridge cap. Thick gauge, so survived shipping. Great value.
I purchased several 8' corner section and they came dirty and lightly corroded. I believe they are stored outside at Greenhouse Megastore's supplier. Being a Aircraft Sheet metal Specialist; I had to clean and remove several bad spots of corrosion from the surface, then treat with Alodine to stop corrosion progression. I then final treated the section with Strotium Chromate Prime, Zinc Chromate will also work. If you follow these steps safely you will be very happy with the product. The price is hard to beat and worth the extra effort of cleaning upon arrival and I will order again.
