Thickness

If the door core is made of glass or a silver mirror, it's typically around 5mm thick. However, if a wooden core is used, 10mm thickness is recommended for better stability and durability. Some manufacturers cut costs by using thinner wood boards—like 8mm or even 6mm—which can lead to problems over time. Thin boards are more prone to warping, swaying, and deformation, which may cause issues with the sliding track, making the door difficult to move smoothly. This can significantly affect the user experience and the overall quality of the product.

Paint Surface

A high-quality paint finish involves a double-layer spray process, including dust removal and impurity elimination, which enhances adhesion and ensures the surface doesn’t peel off easily. Large manufacturers often use advanced technology and in-house processing to achieve a smooth, even, and detailed finish. In contrast, some small producers simply bake the surface without proper treatment, leading to poor texture, peeling paint, and an unattractive appearance. Brands like Sophia, Ocean Gate, Nature Doors, and Top Solid are known for their attention to detail and high-quality finishes.

Plate Material

Sliding doors are commonly made from wood-based panels such as fiberboard or particleboard, which can release harmful substances like formaldehyde. Many low-quality manufacturers use substandard materials with excessive formaldehyde levels, posing health risks, especially in colder regions where windows and doors are kept closed for long periods. Choosing a reputable brand that uses safe, environmentally friendly materials is essential for long-term comfort and safety.

Pulley Material

The pulley is one of the most critical components of a sliding door. There are various types on the market, including plastic, metal, and carbon-fiber pulleys. Metal pulleys are durable but can be noisy when sliding. Carbon-fiber pulleys with roller bearings offer smooth movement, long-lasting performance, and resistance to wear. They also have a closed structure that prevents dust from entering, making them ideal for dusty environments like northern areas. Low-quality plastic pulleys, on the other hand, tend to wear out quickly, causing uneven movement and difficulty in opening and closing the door. Some models lack anti-jump mechanisms, increasing the risk of derailment and unsafe operation.

Warranty

Some poorly established manufacturers may promise a warranty during sales, but once the product is installed, they may avoid responsibility when issues arise. It’s important for consumers to research the manufacturer’s reputation and ensure they receive a warranty card after installation. Sliding doors are expensive items, and a solid warranty guarantees peace of mind and reliable after-sales support.

Style

Aluminum sliding doors come in different styles depending on the region. Northern designs tend to be heavier and more stable, often featuring grid patterns with a distinctive Tanger look. Southern styles, on the other hand, are more diverse, with intricate glass patterns like flower lattice, ice sculpture, shallow carving, and crystal shell effects. Choosing a style that matches your home decor and climate conditions can enhance both aesthetics and functionality.
