Detailed Overview of Invisible Grills for Schools
Invisible grills are an advanced safety solution for schools, ensuring security, visibility, and durability while maintaining an open and well-ventilated environment. Made from high-tensile stainless steel cables coated with a protective layer, they act as a secure yet nearly invisible barrier that enhances safety without obstructing views.
1. Features of Invisible Grills for Schools
a. Material Composition
- Stainless Steel (SS316 or SS316L): Strong, rust-resistant, and long-lasting.
- Protective Coating (Nylon/PVC): Adds durability and ensures safety.
- Wire Thickness & Strength: Available in 2mm to 3mm diameters, with a tensile strength of 400–2000 MPa, making them highly secure.
b. Safety & Security
- Prevents accidental falls from classroom windows, balconies, and terraces.
- Protects students from unsafe areas, such as staircases, corridors, and open spaces.
- Withstands high impact (200–300 kg force), ensuring robust protection.
- Acts as a deterrent against unauthorized entry or vandalism.
c. Visibility & Aesthetic Appeal
- Provides an unobstructed view, allowing teachers and staff to supervise students easily.
- Unlike traditional grills, it does not make classrooms feel closed-off or claustrophobic.
- Enhances natural lighting and ventilation, creating a comfortable learning environment.
d. Hygiene & Maintenance
- Rustproof & Anti-bacterial: Ensures a germ-free environment, crucial for schools.
- Fire-resistant: Unlike iron grills, stainless steel cables do not catch fire, ensuring extra safety.
- Easy to clean & low maintenance: No need for frequent painting or repairs.
2. Applications of Invisible Grills in Schools
