电梯门套是电梯出入口的装饰保护部件，看似只是一个“框”，实则承担着装饰、保护、防火三重功能。它是电梯的“门面担当”，也是建筑细节品质的直接体现。

The elevator door frame is a decorative and protective component at the entrance and exit of the elevator. It may seem like a "frame", but in reality, it serves three functions: decoration, protection, and fire prevention. It is the facade of the elevator and a direct reflection of the quality of building details.

电梯门套分为小门套和大小门套两类。 小门套是电梯厂家出厂标配的部件，仅覆盖门框周边较窄区域；大门套则覆盖整个候梯厅墙体，装饰性更强。从材质选择看，不锈钢门套是目前家用电梯和普通住宅非常常见的配置，造价通常在几千元，具有防撞耐造、防水防潮的优势。大理石门套则自带“豪宅光环”，天然纹理和温润光泽能瞬间拉高空间档次，但造价昂贵，且存在脆裂风险，搬运大件家具时容易磕碰受损。

Elevator door frames are divided into two categories: small door frames and large and small door frames. The small door frame is a standard component for elevator manufacturers, covering only a narrow area around the door frame; The gate cover covers the entire wall of the waiting hall, with a stronger decorative effect. From the perspective of material selection, stainless steel door frames are currently the most common configuration for household elevators and ordinary residential buildings, with a cost usually in the thousands of yuan. They have the advantages of anti-collision, durable, waterproof and moisture-proof. Marble door frames come with a luxurious aura, with natural textures and warm luster that can instantly elevate the spatial level. However, they are expensive and pose a risk of brittle cracking, making them prone to damage when moving large furniture.

不锈钢门套的技术要求比普通装饰材料更严格。 根据《GB7588-2003》规定，电梯门套需在5cm×5cm范围内承受300N静力和1000N撞击力，以防止搬运重物或电动车进出时造成损坏。防火性能方面，电梯门套燃烧性能应满足B1级要求，部分产品会在边框内置防火衬板以提升防火等级。防水性能同样重要，门套需达到浸泡24小时不变形不开裂的标准。

The technical requirements for stainless steel door frames are stricter than those for ordinary decorative materials. According to GB7588-2003, elevator door frames are required to withstand a static force of 300N and an impact force of 1000N within a range of 5cm × 5cm to prevent damage during the handling of heavy objects or the entry and exit of electric vehicles. In terms of fire resistance, the combustion performance of elevator door frames should meet the B1 level requirements, and some products will have fireproof lining boards embedded in the frame to enhance the fire resistance level. Waterproof performance is equally important, and the door frame should meet the standard of no deformation or cracking after soaking for 24 hours.

安装方式持续演进。 现代电梯门套多采用装配式结构，由可拆装的上梁、左边框、右边框通过插接方式组装而成。西奥电梯于2025年申请的专利技术，通过连接组件实现大门套与小门套的快速插接固定，提升了安装效率。浙江建工同年申请的模具专利，则通过定位杆固定焊接角度，提高了焊接精度。

The installation method continues to evolve. Modern elevator door frames often adopt an assembled structure, consisting of a detachable upper beam, left frame, and right frame assembled through plug-in connections. The patent technology applied for by Theo Elevator in 2025 achieves fast insertion and fixation of the main door frame and small door frame through connecting components, improving installation efficiency. The mold patent applied for by Zhejiang Construction Engineering in the same year improved the welding accuracy by fixing the welding angle with a positioning rod.

材质选择需结合预算和风格。 预算有限、追求实用的家庭，304不锈钢门套是稳妥选择，建议选黑钛或古铜色比银色更显出彩。预算充足、追求视觉效果的，可考虑大理石或金属仿石纹门套。无论选择哪种材质，底部收边都需格外注意——这是非常容易受潮和被推车撞击的部位，不锈钢门套的底口一定要收边严密。

Material selection should be based on budget and style. For families with limited budgets and a pursuit of practicality, 304 stainless steel door frames are a safe choice. It is recommended to choose black titanium or antique bronze colors that look more luxurious than silver. For those with sufficient budget and pursuing visual effects, marble or metal imitation stone patterned door frames can be considered. Regardless of the material chosen, special attention should be paid to the bottom edge closure - this is the most susceptible area to moisture and impact from carts, and the bottom opening of the stainless steel door frame must be tightly closed.
