Aluminum Sheet for Main Door Sizes, Thickness & Price Guide
Aug 25 26
When selecting main doors, aluminum doors offer significant advantages—including corrosion and rust resistance, impact durability, and versatile aesthetics—making them far superior to traditional iron, wood, or zinc alloy doors. They are highly adaptable, particularly suitable for humid regions and coastal areas exposed to salt spray, and are an excellent choice for high-quality home installations in self-built houses and villas.
I. Standard Sizes for Aluminum Panel for Doors
The sizes of aluminum sheet for door fall into two categories: standard universal sizes and personalized custom sizes; compatibility with the door opening dimensions is the critical factor. Panel dimensions directly affect the fit of the door, its overall visual appeal, and serve as the primary basis for pricing.
1. Standard Sizes for Typical Residential Apartments
Entry doors for standard residential apartments are predominantly single-leaf designs with highly standardized opening dimensions. The mainstream standard size for finished aluminum single-leaf doors is 2100mm × 900mm. These are widely available and highly versatile, fitting the vast majority of high-rise residential openings without the need for on-site trimming, resulting in shorter installation times and excellent cost-effectiveness. For larger apartments with wider openings, "mother-and-son" doors (unequal double doors) are often chosen; the standard size is 2100mm × 1200mm, providing a wider passage and allowing for more natural light.
2. Custom Sizes for Self-Built Houses and Villas
Entry doors for self-built houses and villas prioritize a grand, premium aesthetic. As there are no fixed standards for door openings—which tend to be larger—double-leaf or four-leaf door styles are commonly used. Mainstream custom height ranges from 2400mm to 3500mm, and width ranges from 1500mm to 3000mm. The market currently supports custom dimensions to fit any opening size; however, custom models carry a higher unit price and require a longer production lead time.
3. Key Purchasing Tips
Measurements must be based on the actual net dimensions of the door opening on-site; simply relying on floor plan data is insufficient. Construction processes such as wall plastering or tiling can reduce the actual opening space. Therefore, precise measurements of the height, width, and wall thickness are essential to avoid issues such as panels being too large to install or too small, which could lead to gaps allowing air or water leakage.
II. Entrance Door Aluminum Panel Thickness
1. 4mm Aluminum Panel (Cost-effective Standard Option)
The 4mm aluminum panel is a common standard thickness for residential doors. It offers adequate hardness and sufficient resistance to daily impacts and scratches for household needs. It supports minimalist flat designs and shallow relief patterns, balancing basic aesthetics with practicality—making it ideal for high-rise apartments and smaller homes. A common configuration pairs a 4mm front panel with a 2mm back panel; the front ensures structural integrity and visual appeal, while the thinner back panel reduces weight and controls costs without compromising stability. It is a highly cost-effective choice for home use, avoiding unnecessary performance overkill.
2. 6mm Aluminum Panel (Preferred Choice for General Residential Use)
The 6mm aluminum panel represents a mainstream mid-range option, offering significantly improved hardness, structural stability, and deformation resistance. It allows for intricate relief work, three-dimensional carvings, and "light luxury" styles. The door feels solid and substantial when tapped, offering a premium quality far superior to 4mm panels. Suitable for a wide range of settings—including large residences, mid-rise apartments, and standard self-built homes—this thickness strikes an ideal balance between aesthetics, durability, and cost-effectiveness, making it a popular choice among homeowners today. A classic configuration pairs a 6mm front panel with a 2mm back panel, providing rich visual depth and resistance to denting or cracking over long-term use, while accommodating various personalized carved designs.
3. 8mm and Thicker Aluminum Panels (High-End, Durable Option)
The 8mm thickened aluminum panel represents a high-end specification. Exceptionally solid and robust, it offers superior resistance to forceful impacts, wind pressure, and corrosion. It supports exquisite, full-bodied 3D carving craftsmanship, delivering a distinctively premium feel. These panels are specifically designed for villas, detached homes, street-facing properties, and locations exposed to harsh environments—such as coastal areas prone to high corrosion and typhoons. They withstand prolonged exposure to intense sunlight, wind, and rain without deforming, fading, or rusting, offering a lifespan of several decades.
III. 2026 Export Price Guide for Aluminum Sheet for Entrance Doors
In August 2026, the FOB export price for virgin, bare aluminium sheet for door price remained stable at 185–380 USD/m², with minor fluctuations based on sheet thickness, specifications, and order volume. Considering London aluminum prices and global supply-demand dynamics, export prices for these substrates are experiencing minor short-term volatility but are generally stabilizing; with no risk of significant price swings in the fourth quarter of 2026, this period presents an excellent opportunity for stocking up.
Aluminum prices are projected to rise steadily in 2027, driven by the release of global demand for infrastructure and home renovation, alongside factors such as tight industry production capacity and low inventory levels; consequently, sheet prices are likely to see a moderate increase, with little room for a significant drop. It is recommended to procure materials for small, sporadic orders on an as-needed basis, while considering locking in prices for large, long-term full-container project orders to effectively hedge against the risk of rising costs.
