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.

A Solution for Our Industry’s Thermal Challenges
In Santa Rosa, where heat and humidity can be a problem in the summer, we realized the need to create a product line that combated these unique challenges for our customers.
Our Artisan Thermal Series is composed of cutting-edge glass-reinforced polyetherimide (GRP).
This material is a great deflector of heat and a solid building material, making it the ideal building block for our steel window frames in Santa Rosa.
In Santa Rosa, many of our competitors simply use insulated glass, which doesn’t nearly do the job of restricting thermal transfer from the glass to the frame of your window or door.
A lot of our competitors also have limited design options when it comes to developing energy-efficient Santa Rosa steel windows and doors.
In contrast, we have an official patent for this product series that gives us free rein to customize our energy-efficient windows and doors the way we choose.
This allows a client to lower their energy bills and achieve a modern design that will complement their property.
