Brombal Materials Facts 04/12/2015

At Brombal USA, we offer a wide range of materials to suit your needs, whether it would be for a residential or commercial project.   We have come up with a couple of key facts for each of the 5 materials we offer:


1. Our steel goes through multiple processes to ensure longevity.  First, all sections go through a skin-passing process which applies galvanization to both sides of the steel before it is formed into a section.

2. We offer 2 finishing options which offer exceptional durability. First is a traditional powder coating process where the finish applied and baked on creating a durable long lasting finish.  Second is a 5 step painting process with an adhesive primer and multiple coats of durable paint.  Either option allows for a variety of colors to choose from using the RAL color system.

1. Our Bronze/Brass contains 67% Copper, which creates a high resistance to corrosion, and 33% Zinc which provides the necessary mechanical properties such as hardness and tensile strength. Our Brass material has the prestige of bronze due to its beautiful patina and high resistance to corrosion, which make it appealing to almost any project.

2. Bonze/Brass creates a self-protecting patina generated by the natural oxidation process which makes the final product ideal for marine environments.

1. CorTen steel is a high-resistance self-passivating alloy containing copper, chrome and phosphorus, characterized by a high resistance to corrosion with excellent tensile strength. The alloys are  are self-protective through the formation of a superficial coating that prevents the progressive extending of the corrosion process. This self-protecting layer creates the warm brown tones over the surface which give it that unique appearance.

2. Brombal was the first manufacturer to use this material for doors and windows, 

Stainless Steel:
1. Available in both a 304 and 316L marine grade, this material is perfect for marine and corrosive environments.

2. The physical features of stainless steel allow for narrow sightlines sections which require minimal maintenance. 

3. Multiple finishes are available such and scotch brite, brushed, mirror and even a blackened finish.

1. Bi-Metal allows the flexibility of choosing 2 different types of materials to be combined, 1 for the interior and 1 for the exterior.

5 Benefits of Steel Over Aluminum 13/11/2015

Steel Material from Brombal USA is made from a specific alloy, the FeP02 with a GZ200 hot zinc coating. This protects the profile from oxidation from both inside and outside of the face. It is finished through a skin-passing process, which allows a better paint grip. Steel is available in a variety of colors in polished, semi- polished or sable finishing.

Steel has many advantages over the weaker material, aluminum. We at Brombal USA decided to come up with 5 benefits that will help you understand your options with steel windows and doors.

1. Steel is a better choice than aluminum for thermally-broken fenestration… why? Steel insulates 5x better than aluminum. Also, steel unit sizes can be much larger than aluminum units. This allows for narrower frame dimensions while still offering large expanses of glazing. By reducing the ratio of frame sightlines to glass the overall unit thermal performance is increased.

2. Structurally steel is 3x stronger than aluminum. This translates into the ability to fabricate the ever growing demand for larger sized door and window frames while maintaining the best structural integrity in the fenestration industry.

3. Brombal steel profiles are “green”. They are made from 100% recycled steel… oh and if you want them in GREEN we have that covered as well. Powder coating color options are nearly infinite. Not only does the high efficiency thermal break save your pocket book money Brombal also helps to save the planet by our “green” manufacturing processes.

4. Have you heard of the term “shelf life”? In construction lingo we use the term “sustainability”. When you consider the overall costs of a product the “sustainability” of that product must enter the equation. Steel windows and doors have this type of durability. If cared for properly they can outlive the structure they are placed in. Studies show that steel windows can easily last and continue to function for much longer than aluminum, wood, or vinyl products, even as much as 3 – 4 times longer.

5. It’s hard to put a price tag on the aesthetic value of steel windows but let’s just say that steel windows have an enduring quality that the most discernible architects, builders, and homeowners recognize. It starts with the simple crisp outlines of the frames which envelops the often heard adage that “less is more”. Windows are made to look through not at. They frame the landscape and allow light to enter the structure. Steel provides this advantage and more… although the frames sizes are subtle steel is a strong and bold material that exudes confidence and style. It has a way of standing out in architecture symbolizing strength and durability.

4 Things You Didn’t Know About Cor-Ten Steel 20/10/2015

The intense richness of a Cor-Ten finish bestows a warm, natural, yet at the same time extremely elegant look. Its distinctive appearance is a result of an oxidation process which forms a protective patina that remains unchanged over the years. Brombal USA would like to share five facts about our Cor-Ten Steel material that you may have not known:

1.) Cor-Ten Steel is Thermally broken
Like all materials we offer at Brombal USA, our Cor-ten is thermally broken material. Ebe and OS2 thermally broken sections are bonded together using two materials: the first is a fiberglass reinforced extrusion and the second is a high-density polyurethane resin injected under high pressure. This process firmly joins the frame sections together, ensures a continuous bond, and provides thermal insulation while maximizing structural strength. After years of intense research, the OS2 was born providing narrow sightline, thermally broken window and door systems.

2.)  Cor-Ten is Weathered Steel
What gives Cor-Ten it’s aged, rustic look?   Cor-Ten steel is created when the steel forms a layer of rust, protecting the material against moisture, and slowing the corrosion process.  Although the material may be just a couple months old, it can appear as from past decades.  For example, the Barclays Center in Brooklyn, NY has a Cor-Ten exterior structure.  Over 12,000 pieces of steel were weathered at a plant in Indiana, and then put through multiple wet-and-dry cycles a day to give that rustic look.  In just a few short months, the Cor-Ten on the Barclays Center has the same weathered steel that would naturally take 6 years.

3.) What’s In the Name?
Cor-Ten steel is a high tensile strength, corrosion resistant, steel alloy, containing copper, chromium and phosphorus. The name (Cor-Ten) reflects the special properties of this allow: corrosion resistance (Cor) and high tensile strength (Ten). These properties make Cor-Ten steel particularly suitable for use in any environment.

4.) Cor-Ten Contains Protective Rust Layer
During the transformation of Cor-Ten, the large rolls of Cor-Ten steel are cut to the required width and rolled to the specific profile section. Upon exposure to air, the patina process begins which creates a protective layer of rust over the surface. Left untreated, the rust will create an ever changing appearance. A surface wax treatment can be applied which will stop the continued rusting and will provide a protective barrier against the elements.
