An Invisible Grill system is only as strong and durable as the quality of the stainless steel cables used within it.
The cable is the true heart of the entire system.

At Mirowawa, we manufacture premium Mirowawa Invisible Grill Systems engineered for superior safety, durability, aesthetics, and long-term performance. Every component is carefully selected and designed to meet the highest standards of quality and reliability.

While many installers focus attention on aluminium frame weight, profile thickness, or other secondary details, the real factors that determine long-term safety, durability, and performance are:

• The grade of stainless steel used 
• The wire rope construction 
• The quality of the polymer coating 
• Corrosion resistance in outdoor environments 
• The quality of fasteners and installation hardware 

A premium Invisible Grill installation must therefore be engineered from the inside out — beginning with the cable itself.

The market today is flooded with low-grade and counterfeit products where inferior stainless steel such as SS202 or other low-quality materials are coated with nylon and falsely marketed as “SS316.”

In many cases, the nylon coating itself is simply printed with “SS316,” while the inner cable does not meet genuine marine-grade standards.

Although such products may initially appear similar, poor-quality cables can eventually suffer from:

• Rust and corrosion 
• Loss of tensile strength 
• Sagging over time 
• Cracking or yellowing of the coating under UV exposure 
• Premature deterioration in coastal and humid environments 

For this reason, verified high-quality stainless steel cables with advanced protective coatings are essential for long service life

We recommend premium 12+1 stainless steel wire rope construction constructions for superior dimensional stability and reduced long-term sagging.

High-quality cable construction ensures:

• Better strength distribution 
• Improved flexibility 
• Greater structural stability 
• Long-term tension retention 
• Enhanced durability under continuous outdoor exposure

The protective coating applied over the stainless steel cable plays a critical role in preserving both appearance and durability.

We recommend:

• CLS-coated cables for enhanced corrosion resistance 
• Specially modified UV-inhibited nylon and advanced polymer coatings designed to resist: 
  • UV degradation 
  • Moisture penetration 
  • Yellowing 
  • Cracking 
  • Environmental wear 

These coatings help protect the inner stainless steel cable while maintaining clarity, flexibility, and long-term outdoor performance.

The quality of fasteners used in an Invisible Grill installation is equally important.

Low-quality screws, anchors, or fixing systems can allow water seepage into parapet walls and concrete structures, leading to:

• Water leakage 
• Rust formation 
• Concrete damage 
• Loosening of the installation over time 

For reliable long-term performance, corrosion-resistant fasteners and proper installation practices are essential.

Mirowawa Invisible Grill Systems are designed and manufactured with a strong focus on:

• Premium-grade stainless steel cable quality 
• Advanced polymer protection technology 
• Strong and stable cable constructions 
• Long-term corrosion resistance 
• Superior aesthetics and finishing 
• Reliable installation engineering 

Our goal is to provide Invisible Grill Systems that combine safety, elegance, strength, and long service life — making Mirowawa one of the most trusted and premium solutions in the industry.
