Gate & Barriers Solutions for Commercial & Industrial Access
Sliding Gates
Sliding gates move laterally along a fixed path to secure entrances where space is limited or where wider openings are required. Instead of swinging inward or outward, they slide parallel to the boundary line, making them an efficient and practical solution for properties with restricted driveway depth. Available in both tracked and cantilever designs, sliding gates are particularly well-suited to industrial and commercial sites, offering smooth, reliable operation, high levels of security, and reduced mechanical wear compared to traditional hinged gates.
Cantilever sliding gates glide above ground without the need for a track across the driveway opening. Supported by a counterbalanced framework and roller assemblies mounted to the side, they are especially suitable for uneven surfaces, sloped driveways, or areas prone to debris, snow, or standing water. Because there is no ground track to obstruct movement, cantilever systems typically require less ongoing maintenance and deliver consistent performance in challenging site conditions.
Bi-Folding Gates
Bi-folding gates are designed for locations with limited space and high traffic flow. Unlike traditional swing gates, they fold in sections as they open, reducing the movement arc and taking up minimal room within the entrance area. This makes them ideal for sites with restricted driveway depth or where vehicles and pedestrians need efficient access.
With rapid opening and closing speeds, bi-folding gates help maintain smooth traffic flow while enhancing security by limiting the time an entrance remains open. They are well suited to commercial premises, logistics hubs and distribution centres.
Built for durability and reliable perimeter protection, bi-folding gates can be fully automated and integrated with access control systems such as intercoms, ANPR cameras, swipe cards, and keypad entry, ensuring secure and controlled access at all times.
Rising Arm Barriers
Automatic rising arm barriers are an efficient solution for controlled vehicle access at car parks, commercial developments, and industrial sites. These systems operate by lifting a horizontal arm to permit entry or lowering it to restrict access, providing a clear and highly visible method of traffic control. They offer simple yet effective access management in locations where perimeter security requirements are lower than those requiring full-height gates.
Designed for reliability and frequent daily use, rising arm barriers are well suited to environments with steady vehicle flow. Their quick opening and closing speeds help maintain smooth traffic movement while ensuring only authorised vehicles can enter.
These systems integrate easily with intercoms, loop detectors, keypads, ANPR systems, ticketing machines, and wider access control platforms, allowing for tailored operation to suit specific site requirements. With options for safety sensors, LED lighting, and durable arm materials, rising arm barriers provide a practical, cost-effective solution for modern vehicle access control.
Swing Gates
Swing gates operate by pivoting on hinge posts and are available in single-leaf or double-leaf configurations, depending on the width of the entrance and site requirements. They are a versatile and widely used solution for moderate-traffic entrances across commercial, industrial, and residential settings.
These gates can be fully automated and integrated with a range of access control options, including intercoms, keypads, remote controls, and card readers, allowing for secure and convenient operation. Their straightforward mechanical design makes them a dependable and cost-effective choice for many sites.
Swing gates do require sufficient clearance to open inward or outward, so adequate driveway depth and lateral space must be considered during planning. Where this movement is possible, they provide a reliable, durable, and aesthetically adaptable entrance solution.
Parking Bollards
Parking bollards provide a practical and highly effective solution for controlling vehicle access and protecting designated spaces. Suitable for commercial premises, retail parks, office developments, apartment complexes, and private car parks, bollards help prevent unauthorised parking while maintaining convenient access for approved users. They are particularly useful in areas where individual bays, pedestrian zones, loading areas, or sensitive building frontages need clear protection.
A range of options is available to suit different operational and security requirements, including manual lift-out bollards, fold-down models, and automatic rising bollards for higher-security applications. Automatic systems can be integrated with remote controls, keypads, or wider access control platforms for seamless operation.
Robustly constructed from durable materials, parking bollards are designed to withstand frequent use and potential vehicle impact. Compact and space-efficient, they provide reliable protection for buildings, pedestrian areas, and reserved parking bays while offering a straightforward and cost-effective access control solution.
Access Control & Integration
All SDG gates and barrier installations can be integrated with modern access control systems, including intercoms, induction loops, safety loops and keypad entry. This ensures seamless operation and improved security for staff, visitors and vehicles entering your site.
Does SDG maintain and repair gates and barriers?
Yes, SDG provides comprehensive maintenance and repair services for all types of gates and barriers, including those not originally installed by us. Our team carries out regular servicing to ensure smooth operation, prevent wear and tear, and maintain full compliance with UK safety regulations. We can inspect, repair, or replace mechanical components, motors, safety devices, and access control systems to keep our site secure and operational. Scheduled maintenance helps reduce downtime, extend the lifespan of your equipment, and ensure that all gates and barriers continue to function safely and efficiently for staff, visitors and vehicles.
Can existing gates be automated or upgraded?
In many cases, existing manual gates can be upgrade with automation, safety devices and access control systems to improve convenience, security, and operational efficiency. Upgrades are usually possible when the gate structure is in good condition, the foundation is stable, and there is sufficient space for motors, tracks, or pivot mechanisms. However, automation may not be feasible if the gate is structurally weak, severely damaged, or if site constraints prevent installation of required equipment. A professional site survey is essential to determine whether your current gates can be safely and effectively upgraded.
What factors determine the best gate or barrier for my site?
The best solution depends on available space, traffic volume, security requirements, ground conditions and whether automation or access control is needed. A site survey helps identify the most suitable option.
How long does gate or barrier installation take?
Installation time vary depending on the type of system, site conditions and groundwork requirements, but mot industrial gate or barriers installations are completed within a few days.
Do you provide nationwide coverage?
Whilst we are based in Lincolnshire, SDG delivers gate and barrier installation, servicing and maintenance across the UK, supporting commercial, industrial and public sector clients nationwide.
Is SDG a member of any gate or barrier-related associations?
Yes, SDG is a member of recognised trade bodies within the commercial and industrial doors sector. We are proud members of the Door & Hardware Federation (DHF), the UK’s leading trade association and centre of excellence for companies involved in the manufacture, installation, and maintenance of doors, gates, barriers, and associated hardware.
Are your gates and barriers protected by warranty?
Yes, all our gates and barriers are backed by a 12-month warranty. Please refer to our terms and conditions for full details.
