Two Sizes, One Complete System
Our Aluminium Sections for Doors and Windows come in two matching widths. The left section is 158mm wide, and the right section is 105mm wide. They are designed to work together as a complete system.
The 158mm left section includes top tracks in 2.0mm and 1.4mm, a 40×65 frame in 2.0mm and 3.0mm, a 30mm high frame in 1.4mm, a standard frame in 2.0mm, a 45mm high exposed drain track in 1.8mm, a 42mm high hidden drain track in 1.4mm, and a flat track in 1.4mm.
The 105mm right section includes top tracks in 2.0mm and 1.4mm, a 40×100 frame in 2.0mm, a standard frame in 1.4mm and 2.0mm, an exposed drain track in 1.8mm, a 40mm high hidden drain track in 1.4mm, and an 8.5mm flat track in 1.4mm.
We have been manufacturing aluminum profiles in Foshan for 15 years. We also operate a warehouse in Hefei, which has been running steadily for 5 years. These standard sizes are regularly stocked, allowing us to ship quickly.


Choose Exposed or Hidden Drainage

Our exposed and hidden drain track designs meet different installation requirements. The exposed drain track provides faster drainage, making it suitable for rainy areas or high-rise projects. The hidden drain track provides a cleaner appearance and works well for projects that focus on visual design.
The wall thickness options for both left and right sections are the same, helping maintain a balanced window structure. You can select different thicknesses based on building height and wind pressure requirements.
We allow mixed orders of different thicknesses, colors, and models in one container. For existing sections, we provide free samples, and you only need to cover the freight cost. Before packing, we inspect every piece for dimensional accuracy and surface defects such as burrs or deformation. We also accept third-party inspections.
The standard payment term is a 30% deposit, with the balance paid before loading. Our after-sales team responds to quality issues within 24 hours.

Flexible and Durable
These Aluminium Sections for Doors and Windows are mainly used in residential sliding windows, balcony sliding doors, shopping mall sliding doors, and project sliding systems. The multiple thickness and track options provide flexibility for different applications.
The track system has high precision, allowing the rollers to operate smoothly without jamming. The sealing and waterproof performance are also reliable, helping prevent leakage during rainy weather.
Before ordering, we provide accurate section data and load references. During production, we send progress photos and videos. After sales, we handle dimensional deviations and surface defects promptly.
We support Foshan factory delivery and FOB shipment from Foshan or Shenzhen port. The sprayed surface comes with a 5-year warranty under normal use. We hold ISO9001 and CE certifications.
We do not focus on being the largest supplier, but we maintain strict control over track straightness and dimensions in every batch. If you need sliding door and window sections with high track accuracy and complete specifications, we can provide long-term support.
