Modern Heavy‑Duty Thermal‑Break Sliding Door

Structural Design

• Heavy‑duty thermal‑break structure: 6063‑T5 aluminum alloy profile with 2.2 mm wall thickness provides high load‑bearing and anti‑deformation capacity. It supports extra‑wide and extra‑high door sashes and fits for panoramic curtain‑wall style installation.

• Flexible multi‑track adaptation: Supports double‑track (150mm), triple‑track (225mm), four‑track and five‑track sliding combinations to satisfy various wall thickness and opening requirements. Sashes can slide freely for partial ventilation or full panoramic opening.

• Narrow‑frame appearance: Well‑controlled frame width balances structural strength and visual permeability.

Performance Parameters

• Sealing and compression resistance: Watertightness 550Pa, air tightness 1.0m³/(m·h), wind‑pressure resistance 5.0kPa, suitable for rainy‑windy climate regions.

• Thermal insulation & energy‑saving: U‑value of 0.35 combined with 5mm+20A+5mm insulated hollow glass effectively blocks heat transfer, applicable for severe cold and hot climate zones.

• Sound insulation & noise reduction: 35dB sound insulation performance builds a quiet indoor living environment.

Configuration & Craftsmanship

• Profile treatment: Powder‑coated surface enhances weather resistance and aesthetic effect.

• Glass configuration: 5mm+20A+5mm insulated hollow glass balances thermal insulation and daylighting requirements.

• Hardware system: Custom‑made Chinese‑produced fittings tailored for heavy‑duty sliding structures.
