\"Aluminum<\/figure>\n

You have just had your aluminum gate installed and are quite pleased with the result. However, two years later, the paint is blistering in places, the frame is slightly warping, or the lock no longer turns as smoothly. Yet, it was aluminum, supposedly almost indestructible. The problem does not stem from the material itself. It comes from a detail no one considers at the time of purchase: the thickness of the profiles. This parameter is invisible to the naked eye, and low-cost manufacturers exploit it to drive prices down. This is what makes the difference between a gate that lasts and a gate that wears out. <\/p>\n

Profile Thickness: The Criterion No One Checks<\/h2>\n

When choosing an aluminum gate, one typically looks at the design, color, and price. Rarely is the profile thickness considered. Yet, this is where everything truly matters. <\/p>\n

A professional-grade profile measures at least 2 mm on the main uprights and crossbars. Entry-level gates can go down to 1.2 mm, sometimes even less. The difference is invisible once the gate is painted, but it becomes apparent with the first strong winds or after a few opening cycles. <\/p>\n

A profile that is too thin results in a frame lacking rigidity. The leaf deforms, the hinges are strained, and the gap between the two leaves widens. The gate closes poorly, creaks, and eventually jams. This is not an installation defect; it is a material defect integrated during manufacturing. <\/p>\n

Shoddy Powder Coating Leaves Its Mark<\/h2>\n

Another rarely inspected point is the quality of the powder coating. On a reputable aluminum gate, the lacquer layer is applied after a complete surface treatment, including degreasing, chemical conversion, and oven powdering. This process guarantees long-term durability, even when exposed to direct sunlight or coastal environments. <\/p>\n

On a low-end gate, the process is shortened. As a result, the paint lasts one or two years, then begins to chalk, crack, or discolor in patches. If you run your finger over your gate and a whitish powder remains on your skin, it is a sign of failed powder coating. A good treatment complies with the Qualicoat standard, which guarantees finish durability for a minimum of 10 years. <\/p>\n

The Infill, Another Discreet Indicator<\/h2>\n

The infill slats or panels of an aluminum gate are not all equivalent. On quality models, the slats are mechanically fitted into the uprights, sometimes screwed or clipped with a seal. On low-cost versions, they are simply glued or held in place by expanding foam injected inside the frame. <\/p>\n

This system works initially. However, the foam retracts over time and with temperature fluctuations. The slats eventually vibrate in the wind, or even detach. If your gate sounds hollow when you tap it and you feel play in the panels, the infill was likely done cheaply. <\/p>\n

Undersized Accessories and Hardware<\/h2>\n

A gate is not just metal: it also includes hinges, a lock, stops, and leaf retainers. On a quality aluminum gate, these elements are made of stainless steel or corrosion-treated zamak. They are sized to support the actual weight of the leaf and withstand thousands of cycles. <\/p>\n

On an entry-level model, the hardware is often:<\/p>\n
