Side Sliding Sectional Door — RAX Door Technology

01 · Overview

The Solution for Low-Headroom Garages

The side sliding sectional door moves horizontally along wall-mounted tracks, stacking panels to one or both sides of the opening. Unlike overhead sectional doors that require ceiling space for tracks and counterbalance systems, side sliding doors need only 50 mm of headroom above the opening and 130 mm of side clearance. This makes them the ideal solution for garages with low ceilings, exposed beams, ductwork, or sloped roofs where traditional overhead doors cannot install.

RAX manufactures side sliding sectional doors with 42 mm PU foam insulated panels (galvanized steel skins), 2 mm hot-dip galvanized steel tracks, and 72 mm bearing rollers for smooth, quiet operation. The torsion spring system uses 60Si2Mn spring steel rated for 80,000+ cycles, with cable break and spring break safety devices. Panels are available in smooth, stucco, woodgrain, and ribbed textures, with 100+ RAL color options and Decograin wood-grain finishes. Electric automation with soft-start/soft-stop, partial opening (pedestrian access), and customizable gap settings is available.

Side sliding sectional doors are best suited for residential garages with space constraints, workshops requiring full ceiling utilization, wide or irregular openings, and industrial buildings where overhead space is occupied by cranes, conveyors, or storage systems.

02 · Key Features

Engineered for Space-Constrained Openings

Minimal Headroom Required

Only 50 mm of space above the opening for the top guide rail. Ideal for garages with low ceilings, exposed beams, ductwork, or sloped roofs where overhead sectional doors cannot fit.

Side Clearance

130 mm of wall space on one or both sides for panel stacking. Single-slide configuration stacks to one side; double-slide (bi-parting) splits panels to both sides for wider openings.

Insulated Panels

42 mm PU foam core with galvanized steel skins. Optional 50 mm panels for enhanced thermal performance. Inter-panel seals reduce air infiltration. U-value approximately 0.5 W/(m²·K).

Heavy-Duty Track System

2 mm hot-dip galvanized steel tracks with 72 mm bearing rollers. Smooth, quiet operation with minimal friction. Floor-mounted track guides panel movement; top rail prevents lateral displacement.

Spring Safety System

60Si2Mn torsion springs rated for 80,000+ cycles. Cable break protection + spring break protection (blade-type, engages track to brake door). Safety factor >5× door weight.

Electric Automation

Soft-start/soft-stop motor with partial opening (pedestrian access), customizable gap settings, and wireless remote control. Emergency release for manual operation during power failure.

04 · Applications

Where Side Sliding Doors Excel

Low-Headroom Garages

Garages with ceiling height too low for up-and-over or standard overhead sectional doors. Side sliding doors need only 50 mm above the opening. Ideal for basements, converted spaces, and garages with sloped roofs.

Maximum Ceiling Utilization

Homeowners who need to install storage racks, vehicle lifts, or park high-roof vehicles (SUVs, RVs, modified cars) directly under the ceiling. Side sliding doors free up 100% of ceiling space.

Workshops & Utility Spaces

Garages used as workshops, tool rooms, or multi-purpose utility spaces requiring full-width, full-height access. Partial opening feature allows pedestrian access without fully opening the door.

Wide or Irregular Openings

Openings wider than standard up-and-over doors, or irregular shapes (arched, sloped). Double-slide bi-parting configuration supports up to 11 m width. Custom track layouts accommodate unique structures.

Garages with Beams or Ductwork

Garages with structural beams, lighting fixtures, pipes, or roof slopes across the ceiling. Horizontal sliding mechanism avoids top obstacles entirely — no complex overhead track system required.

Modern Architectural Design

Residential and commercial buildings追求 modern, minimalist aesthetics. Side sliding doors provide clean horizontal lines and a contemporary feel. Can be matched with entrance doors for unified appearance.

How much headroom does a side sliding door need?

Only 50 mm above the opening for the top guide rail. This is significantly less than overhead sectional doors (typically 300–500 mm) or up-and-over doors (requires full door height plus mechanism space). Side sliding doors are the ideal solution for garages with low ceilings, exposed beams, or ductwork.

What is the difference between single-slide and double-slide configurations?

Single-slide: all panels stack to one side of the opening. Requires 130 mm side clearance. Maximum width approximately 5,600 mm. Double-slide (bi-parting): panels split and stack to both sides. Requires 260 mm total side clearance (130 mm each side). Maximum width approximately 11,000 mm. Choose single-slide for narrower openings; choose double-slide for wide openings or when side space is limited on one side.

Can side sliding doors be insulated?

Yes. RAX offers 42 mm PU foam insulated panels as standard, with optional 50 mm panels for enhanced thermal performance. Inter-panel seals reduce air infiltration. U-value approximately 0.5 W/(m²·K). However, side sliding doors inherently have more edge gaps than overhead sectional doors, so overall thermal performance is slightly lower. If maximum insulation is required, discuss your specific needs with our engineering team.

Are side sliding doors secure?

Standard features include anti-lift lock and multi-point locking. Optional RC2 burglary resistance certification is available for enhanced security. Electric versions include wireless remote control with rolling code encryption and emergency release for manual operation during power failure. For high-crime areas, specify RC2 certification + reinforced locking points.

What is the maximum size for a side sliding door?

Single-slide configuration: maximum width approximately 5,600 mm. Double-slide (bi-parting) configuration: maximum width approximately 11,000 mm. Height is typically limited by panel stacking space on the side wall. Custom sizes available on request — provide your exact opening dimensions and we will confirm feasibility.

How long do side sliding doors last?

With proper maintenance, side sliding doors last 15–20 years. RAX torsion springs are rated for 80,000+ cycles (approximately 20 years at 10 openings/day). Hot-dip galvanized tracks and panels resist corrosion in humid and coastal environments. Warranty: panels 10 years, automation components 5 years.

Can side sliding doors be automated?

Yes. Electric operators are available with soft-start/soft-stop functionality, partial opening (pedestrian access), customizable gap settings, and wireless remote control. Emergency release allows manual operation during power failure. Some models include integrated LED lighting and smart home connectivity. Manual-to-electric conversion is possible on existing installations.

Do you provide installation?

No — RAX is a pure manufacturer. Doors ship with English installation manuals, wiring diagrams, and remote support. We recommend using a qualified local installer who can verify structural capacity and proper anchoring of the track system.

What is the lead time and warranty?

Standard configurations: 12–20 days. Custom first order: 20–35 days. Repeat orders: 15–20 days. Warranty: panels 10 years, automation components 5 years. Warranty replacement parts shipped via DHL/FedEx in 5–7 days.
