San Jose Custom Steel Doors and Windows
Benefits of Custom Steel Doors
Custom steel doors offer business owners exceptional strength and security. Built to be nearly indestructible, they provide reliable protection for your property, inventory, and staff.
Because steel is one of the most durable materials available, these doors can easily withstand the daily wear and tear of busy commercial environments—especially in areas where large or heavy items are frequently moved in and out. That makes commercial steel doors an ideal choice for high-traffic entrances.
Custom steel doors are also highly energy-efficient thanks to their superior insulation. Portella’s steel doors feature advanced thermal coatings designed for maximum durability and tensile strength, helping to maintain indoor temperatures and reduce heating and cooling costs over time.

The Thermal Window Difference
Thermal windows also do a great job warming your home in the wintertime. They have UV coatings on both the inside and outside to ensure heat reflects back indoors.
