First, the core advantages of tempered glass guardrails
High security
Tempered characteristics: 4 to 5 times the strength of ordinary glass, strong impact resistance (can withstand human impact).
Crushing safety: honeycomb obtuse angle particles after fragmentation, not easy to cut.
Weather resistance: temperature difference resistance (-50 ° C to 200 ° C), UV protection, suitable for outdoor use.
Transparent and beautiful
Unblocked view, suitable for viewing balconies, sea view rooms, etc., to enhance space lighting and visual extension.
It can be paired with metal (stainless steel, aluminum alloy) or wooden handrails in a variety of styles (modern, minimalist, industrial).
Easy to clean and maintain
Smooth surface, dust, rain easy to wash, long-term use is not easy to discolor.
III.Key design specifications and installation requirements
Thickness selection
Single-layer tempered glass: generally 8 to 12mm (10mm is commonly used in residential buildings).
Laminated tempered glass: two pieces of 6-8mm glass + PVB film (higher safety requirements, such as high altitude, children's activity area).
high standard
Civil buildings: guardrail net height ≥ 1.05m (airborne height below 24m), ≥ 1.10m (airborne height above 24m).
Kindergarten/school: ≥ 1.20m, and avoid horizontal railings (anti-climbing).
Fixing method
Point fixed: fixed by metal claw parts (docking claw), the appearance is simple, but the pre-embedded steel structure is required.
Frame fixed: embedded in stainless steel/aluminum alloy groove, stronger stability, suitable for high wind areas.
Foot fixing: The bottom of the glass is fixed with steel grooves + expansion bolts, and a handrail is added to the top.
Collision avoidance measures
Glass edges need to be edged (avoid sharp corners).
Transparent glass can be affixed with anti-collision strips or decorative film (to prompt pedestrians).
IV. Potential drawbacks and solutions
self-explosion risk
Problem: Tempered glass has a self-explosion rate of about 0.3% (caused by the expansion of nickel sulfide impurities).
Solution: choose hot dip treatment (HST) tempered glass, or directly use laminated glass (even if broken will not fall).
Poor privacy
Solution: choose matte, colored glaze, Changhong glass, etc., or stick a privacy film later.
Cleaning problem
Suggestion: Outdoor glass can be coated with nano hydrophobic coating to reduce water stain residue.
Summary: Tempered gla ss guardrail is a choice that combines safety and aesthetics, especially suitable for modern style buildings. If the safety requirements are extremely high (such as high-rise residences), laminated tempered glass is recommended; if the pursuit of cost performance, you can choose a combination of single-layer tempered glass + metal frame.
