What are A-pillars?

Most car owners don’t know much about the structural engineering of their vehicle. They focus on looks, performance, without keeping track of structural elements that require better protection. These components are a part of your vehicle’s frame and will ensure it remains strong enough to travel at high speeds. Some of the most important parts of this frame are A-pillars.

A-pillars are designed to provide vertical support, especially around glass installations like a windshield. They also support your car’s roof, making sure all weaker structures stay in place without damage. These bars are a part of a set of three or four similar pillars. They support the front vertical components located near a car’s hood.

A is followed B, C, and D pillars, all of them supporting different sections of the car. Location, size, and shape of these bars depend on the type of vehicle you own. Long vehicles like a limousine will have more as they require more vertical support. Cars without any roof don’t need A-pillars though these vehicles are rare. Even convertibles have retractable roofs that need ample support.

What kind of problems do they face?

A-pillars are mounted on either side of the windshield so they experience a considerable amount of stress. This is especially true for high-performance vehicles that can reach 200mph. Common problems experienced include:

Friction and stress – This component include two distinct parts, the first one supports your windshield and roof, the other supports your driver’s side and passenger doors. Regular driving places an incredible amount of stress on this component.

Corrosion – Weather conditions, dirt, excessive moisture, bird droppings, etc, can cause extensive corrosion in A-pillars. Corrosion weakens structural integrity, which will place you at risk during driving.

Leakages – A leak is the most common problem with A-pillars. If the seal around these components becomes weak, water can slip past it and damage your vehicle’s interiors. Without proper protective measures, this leak can cause rusting and damage your car further.

Scratches – Flying debris, sand, dirt, or even vandalism can damage A-pillars. Surface paint forms a protective layer, making sure the underlying metal isn’t exposed to moisture or other elements. Scratches or chips compromise this protection, which can place these components at risk.

Good protective measures like Paint Protection Films can keep reduce wear and keep these pillars safe for a long time. Good quality products from XPEL or Suntek have a proven track record and come with 5 to 10 years of warranty.

How does PPF protect A-Pillars?

A convenient and relatively affordable way to protect your A-pillars is to apply a wrap on it. We recommend clear protection film for pillar protection. This material is completely transparent so it will not have any impact your car’s appearance. A film can be easily installed or removed without causing any damage to a car. It is a resilient and safe solution; you can maintain your vehicle’s frame and strength without spending too much money on repairs.

What is the best solution?

People find it hard to believe that a thin layer of plastic is enough to protect metal, but this film is specifically designed for the purpose. This thermoplastic urethane-based compound forms an even layer of protection over A-pillars. PPF has multiple layers that serve different purposes. The first layer provides surface protection against scratches, chips, corrosion, rust, etc.

The materials hydrophobic properties ensure all water and dirt just roll off without causing trouble. There’s little chance of leakages and related problems because this film will form a solid barrier between the outside environment and your car. PPFs second layer adheres to painted metal surface easily, filling any existing cracks or scratches to form a uniform layer. This ensures your film stays in place regardless of driving conditions, weather conditions, and related factors.

If this film is installed properly, it won’t budge. As a self-healing thermoplastic, PPF recovers easily from small surface damage. Even letting your car sit in the sun for a few minutes is enough to heal small scratches or tears. Good quality protective film won’t become yellow with age or sun exposure so you needn’t worry about its impact on your car’s looks.

What do professionals do differently?

Professionals know how these materials work. They understand how to create a seamless finish with no bubbles or edges on its surface. Experienced installers will also wrap the film around an A-pillar’s edge to ensure there are no vulnerable spots for moisture or dirt to settle. Professional installations last longer without requiring a replacement, especially if you choose a film from reliable brands.

Our team has ample experience in this field. We have installed several hundred PPFs in our lifetime so we understand how they perform. Our experts will offer unbiased advice on different film products available today so you can make an informed decision.
