Materials for Grilles and Access Doors: Why We Choose ASA Plastic and Stainless Steel
Why Are Our Grilles and Doors Made from ASA Plastic and DIN 1.4301 Stainless Steel?
When manufacturing our ventilation grilles, inspection doors, and bath access panels, we focus on quality and long-lasting durability. That’s why we carefully choose only the best materials — ones that meet high standards of resistance to external factors while also maintaining their aesthetic appeal. In this article, we’ll explain the advantages of ASA plastic and DIN 1.4301 stainless steel, compare ASA and ABS, and show why our stainless steel products outperform cheaper alternatives or imitations.
ASA Plastic: Built to Last, Even in Harsh Conditions
ASA (Acrylonitrile Styrene Acrylate) is a premium-grade plastic known for its excellent resistance to UV rays, weathering, and chemicals. It's perfect for outdoor use thanks to its long-term color stability and structural integrity — even when exposed to sunlight and extreme temperatures.
Where We Use ASA Plastic:
Ventilation Grilles: Suitable for both indoor and outdoor use, resistant to sun, rain, and frost.
Inspection and Bath Access Panels: Easy to maintain, durable, and stylish to match modern interiors.
ABS ASA
Difference Between ASA and ABS Plastics
We’re often asked why we use ASA instead of the more common ABS (Acrylonitrile Butadiene Styrene). Here’s a quick comparison:
| Property | ASA – Outdoor-Ready | ABS – For Indoor Use Only |
|---|---|---|
| UV Resistance | High – Ideal for outdoor applications | Low – Degrades with sun exposure |
| Color Stability | Long-lasting color, even after years | White turns yellow and may crack |
| Temperature Resistance | Handles extreme weather | Less tolerant of temperature shifts |
| Strength & Flexibility | Balanced and durable | Less strong in demanding conditions |
Thanks to these properties, ASA is clearly the superior choice for products exposed to outdoor environments — like our grilles and access panels.
DIN 1.4301 Stainless Steel: Reliable Strength and Durability
Our stainless steel products — including grilles and doors — are made from high-grade DIN 1.4301 stainless steel (also known as AISI 304). This food-grade steel is one of the most commonly used and reliable types of stainless steel, ideal for construction and ventilation systems.
Advantages of DIN 1.4301 Stainless Steel:
Corrosion Resistance: With 18% chromium and 8% nickel, this steel is highly resistant to corrosion — crucial for outdoor use.
Hygiene & Safety: Used in food and medical industries — non-toxic and easy to clean.
Longevity: Products made from this steel last for decades with minimal signs of wear.
Mechanical Strength: Resistant to stress and wear — even with frequent use and handling.
Why Choose Genuine Stainless Steel Over Imitations?
The market is full of cheaper “stainless-like” materials that don’t offer true durability. Common pitfalls include:
Lower Grades (e.g. 1.4016): Contain less nickel, making them more prone to rust, especially in humid or salty environments.
Fake Stainless Finishes: Often just coated surfaces that wear away quickly, revealing rust underneath.
By using certified DIN 1.4301 stainless steel, we guarantee that our grilles and access doors are not only sleek and modern in appearance — but also built to last, even in tough conditions.
In Conclusion
Choosing ASA plastic and DIN 1.4301 stainless steel ensures our products meet your expectations for quality, durability, and longevity. Whether it’s ventilation grilles, inspection doors, or bath panels, these materials offer a smart investment — combining reliable performance with long-term aesthetic appeal.
