Choosing the right quality security door or screen can be as daunting as most large purchases. When you get a security door, you are within your rights to expect that it will last a long time. Rusty or corroded security installations not only look bad but are also compromised in strength. So, it’s important to pick a both a product and an installer that will go the distance.

Here we outline how corrosion can affect your security door and how to choose, and care for, the best product for your situation.

Security door corrosion

Around 80% of Australia’s population lives on or near the coast, and corrosion from a salt spray can be a real problem for a metal security door. Salt will corrode not only metal, but also concrete, tiles, bricks, mortar, and wood which can cause structural problems.

Another potential cause of metal corrosion is galvanic corrosion. This kind of corrosion occurs when two dissimilar metals such as Stainless Steel and Aluminium come in direct contact either directly or through a conductive substance such as moisture or grime, which can build up around the perimeter of mesh security doors.

If the direct contact between the two metals is prevented by quality beading and seals such as the ones used in Crimsafe products,and the product is kept free from grime or salt build up then there cannot be galvanic corrosion.

How are security doors and windows manufactured?

Preventing corrosion is a crucial point; it’s where most manufacturers will spend their money if the door is made right. When purchasing a steel and aluminium door, the most common method for further protection is Powder Coating the security door.

Crimsafe uses only the toughest materials: 0.9mm diameter, 304-grade structural grade stainless steel wire with high-grade pre-treatment and high durability powder coat technologies are applied to protect the finished product so it will not rust. Crimsafe is the only security screen product in Australia where the mesh is screwed into the frame, using tamper-resistant stainless-steel screws, and clamped down with a patented device called the “Screw-Clamp™.”

You can customise your frame with just about any colour you can think of. Clearview Security works with the largest global manufacturer of powder coatings so you can be sure to find the perfect colour solution to match your space.

Durability of Crimsafe products

Crimsafe products are amongst the most durable security screens and doors on the market. Despite their ability to withstand force and environmental wear and tear, all mesh traps dirt and impurities from the air, giving it a worn appearance over time. Salt, moisture, and airborne impurities can all lead to staining of the mesh coating, reddish marks, or white salt build-up.

There is a huge range of security screens on the market, but if you’re looking at installing security screens in your home, you’ll find that Crimsafe doors from Clearview Security tick all boxes:

Caring for your security door

Since all screens trap dirt and impurities over time, it is important to wash your security products regularly to avoid staining and remove build-up. Keeping your security screens clean prevents build-up of dirt, grime, and salt, lessening the likelihood of corrosion.

Regular maintenance depends on your environment; for most it involves a wash down of frames and mesh with warm water using a soft non-abrasive brush to dislodge dirt and grime, followed by a wipe down. Learn more about how to care for your Crimsafe products.
