RETRACTABLE SECURITY GATES
FEATURES & BENEFITS
There are many benefits to using galvanized steel as your material for gates and fencing. Below are just a few reasons galvanized steel has skyrocketed in popularity with property owners:
Low
Maintenance
Each of our products is coated with an electro-statically applied, powder-coat finish, making it bump and scratch resistant, water-tight, highly resistant to corrosion and easy to maintain.
Rust & Decay
Resistance
Powder-coated and galvanized steel doesn’t decay, like wood or iron alternatives. Our steel alloy provides a strong guard against aggressive vandalism or burglary attempts.
Design
Versatility
View our most popular designs in the gallery above. You’ll see more than one style that will be a beautiful match for your home or shop. The powder coating added during production allows a wide variety of color choices.
Classic or Contemporary
Beauty
You’ll discover that the trellis design of all our models will be a good fit for a classic or contemporary design. View our gallery for examples of how you can customize security bars to protect your property without detracting from the beauty of your home.
Safety
First
The superior engineering and our patented upgrades have brought about a much more easy-to-use retractable security bar system. These are more stable, requiring little to no adjustments over time. Our competitors’ offerings often are a struggle to operate and are more likely to cause an accidental injury.
Environmentally
Friendly
A key “plus” that powder coating has over other finishes is environment and labor safety for the people who work with it. Unlike the typical, solvent-based wet paint, powder coating is a “green” technology. Powder-coating doesn’t produce harmful solvents or airborne pollutants.
