We provide verifiable and actionable knowledge on selecting, measuring, installing, and using attic retractable staircases and basement concealed doors.
This section is compiled by the Maishang product and installation team. For specific dimensions, load-bearing capacity, installation, and after-sales service, please refer to on-site measurements, the corresponding model's technical data, and the terms of the contract between both parties.
First, assess the location of the opening and site conditions, then determine whether it will be ceiling-mounted, wall-mounted, or side-mounted; subsequently, choose manual or electric operation, structural materials, and installation services. Do not place an order solely based on product appearance or a single price.

Top-mounted openings are mainly used for horizontal attic openings, wall-mounted openings are mainly used for exterior walls, and side-mounted openings are mainly used for vertical openings. These three types are not classified by appearance, but by the direction of the opening, the fixing structure, and the way passage is possible.

For low-frequency use and when a simple structure is important, a manually assisted model is worth considering; for high-frequency use and when remote control with one-button opening and closing is preferred, an electric model is more suitable. Ultimately, the choice also depends on the opening, power supply, and on-site installation conditions.

Record at least the net length and width of the opening, the thickness of the floor slab or ceiling, the height from the ground to the opening, the area of the staircase, and any surrounding obstacles. For non-standard sites, it is recommended that the installer conduct an on-site verification.

Most existing renovation sites can be assessed for future installations, but the opening structure, ceiling and wiring locations must be confirmed first, and a plan for protecting, fixing and finishing the finished products must be developed.

Side-opening doors are suitable for most conventional basement entrances; vertical-opening doors flip upwards, requiring inspection of the space above and the opening structure; double-opening doors are suitable for larger openings and can reduce the size of a single door.

Common finishes include ceramic tiles, wood flooring, and stone. To ensure harmony with the surrounding flooring when closed, the paving direction, thickness, joint spacing, and door load-bearing design must be agreed upon in advance.

Outdoor rain protection is a systematic project: door seals are used to reduce water ingress, ground slopes and drainage facilities are responsible for timely removal of rainwater, and extreme weather and regular cleaning and maintenance must also be taken into account.

Maishang's basement concealed doors are uniformly labeled with a load-bearing capacity of 2000 jin (1000 catties). However, the actual project load-bearing capacity still needs to be confirmed based on the door dimensions, finish weight, stress location, installation foundation, and specific model technical documents.
