The Black Railing Planter Box is designed for residential balconies, apartments, hotel-room balconies, office window areas and small terraces. Its narrow structure helps create planting space without taking up too much of the available walking area.
Compact Planter for Balconies and Small Terraces
The Black Railing Planter Box is designed for residential balconies, apartments, hotel-room balconies, office window areas and small terraces. Its narrow structure helps create planting space without taking up too much of the available walking area.
Common lengths range from 400 to 1,500 mm. Standard widths are 180–450 mm, and heights range from 180 to 500 mm.
When aluminium sheet is used, the normal thickness is 1.2–2.5 mm. Steel-sheet versions commonly use material with a thickness of 1.0–2.0 mm.
The planter can be manufactured as a freestanding, wall-mounted or railing-mounted unit. Its dimensions, surface color and installation structure can be coordinated with balcony railings, windows and exterior building finishes.

Drainage and Maintenance Features

Available drainage configurations include bottom drainage holes, side overflow holes and combined water-storage and drainage structures. A water collection tray or drainage tube can also be added to reduce the effect of watering or rainwater on lower floors.
A lightweight removable liner can simplify soil replacement, cleaning and seasonal plant changes.
Before selecting a Black Railing Planter Box, buyers should check the permitted load of the balcony slab, windowsill or railing. The calculation should include the planter body, wet soil, plants, stored water and fixing components.
For wall-mounted or railing-mounted products, the wall structure, railing section and connection position should be confirmed. Installation reliability cannot be judged only by the empty weight of the planter.
Custom Installation Parts and Metal Fabrication
Nantong Yinuo can customize the product according to balcony length, railing type, windowsill dimensions and drainage direction.
Laser cutting, bending, punching, welding and coating processes can be used to manufacture narrow planter bodies, removable liners, water collection structures and installation accessories.
Production is available according to CAD drawings, 3D models or physical samples. The technical team can also discuss adjustments to planter dimensions, fixing methods and internal structures according to the intended application.
For round-tube railings, square-tube railings or wall installation, the connecting parts and mounting positions can be confirmed before production. This reduces the need for additional drilling or accessory modification at the site.
MOQ, Sampling and Final Inspectiont
The minimum order quantity for regular products is 10 pieces. Different colors and styles can be mixed within the same order, which supports projects with several apartment or hotel room types.
A simple standard sample normally requires 5–7 working days. Dimensions, color, drainage and installation structure can be confirmed before mass production.
Standard in-stock products usually require 7–10 working days for production and shipment after the deposit is received.
Before packaging, each planter is checked for sheet thickness, dimensions, welded areas, painted surface, drainage holes and visible appearance. Small products are wrapped with EPE foam and packed in export cartons.
Production photos or videos can be provided regularly. Installation communication and transport-damage support are available after delivery.
