Outdoor Cylindrical Rainproof Cabinet

Yushi outdoor cylindrical rainproof cabinets are tailor-made for wrap-around display screens mounted on utility poles, lamp posts or independent cylindrical bases. Shaped as full or near cylinders, they can house flexible LED screens, multiple curved spliced screens or light strip screens to deliver 360°all-round information display. The cabinet is fully roll-formed from aluminum alloy with laser-welded and polished joints. It is equipped with a rain-proof top brim and water guide trough on the top, as well as drainage holes and flange mounting plate at the bottom, suitable for lamp post screens in urban plazas, scenic guide columns, circular advertising towers and other scenarios.

Product Parameters

Material & Structural Features

The cabinet main body is rolled from thickened galvanized plates with seamless integrated forming, featuring high structural integrity, strong wind resistance and deformation resistance. Its outdoor electrostatic plastic spraying surface resists ultraviolet rays, acid and rain, avoiding rust and color fading after long-term outdoor exposure. The cylinder is fitted with arc-shaped opening doors, with a full circle of weather-resistant sealing strips embedded in door frames for tight sealing. The integrated arc rain shield on top allows rainwater to slide down naturally without water pooling dead zones. Staggered circular air vents are arranged on the cylinder to realize air circulation and heat dissipation while keeping rain out. An adjustable circular inner bracket is installed inside to fit equipment of different diameters. Circular waterproof cable outlets at the bottom enable neat wiring and block standing water on the ground. Anti-rust hinges and anti-theft locks are fitted on door panels for smooth opening/closing and reliable safety protection.

Application Scenarios

Installation Steps

1.Foundation Construction: Pour concrete foundation per flange dimensions and pre-embed anchor bolts.

2.Cabinet Hoisting: Lift the cylindrical cabinet to align with bolts, level it up and fasten nuts.

3.Internal Display Installation: Enter via the top or maintenance door, fix flexible screens or modules along inner wall tracks by pasting or fastening.

4.Wiring: Thread power and signal cables through bottom cable outlets and connect to screen controllers.

5.Sealing Inspection: Tighten all waterproof cable connectors and reset the top rain brim.

6.Power-on Commissioning: Check 360°display effect and calibrate color uniformity.

FAQ

Q1: How to adapt playback content for cylindrical screens?

A: Special-shaped playback software is required to map flat content into circular images.

Q2: How to fix LED modules on the curved inner wall?

A: Curved aluminum profile tracks are pre-installed on the inner wall; modules with curved bottom shells are fastened by screws or magnetic adsorption.

Q3: Is heat dissipation evenly distributed around internal equipment?

A: The surrounding ventilation structure enables full-range air circulation, resulting in small internal temperature difference and balanced heat dissipation.

Q4: Can multiple cylindrical screens be installed on one single pole?

A: Yes. The pole can be fitted with 2–3 segmented independent cylindrical cabinets vertically, connected by flanges. Each segment can display content independently or synchronously.
