Construction Site Fencing & Temporary Gates

Secure Temporary Building Site Barriers, Gates & Fencing

Quality Site gates and Site Hoarding Alternatives

At Alexandra Security, we work closely with main and sub-contractors across the UK construction and demolition sector. Our understanding of the real-world challenges on building sites has led to the development of robust, long-lasting solutions—including SiteGard temporary site gates, CraneGard tower crane barriers, and flexible temporary fencing systems. Designed for fast installation and reliable performance, our systems help you secure your site without compromising efficiency.

Safer Site Entry with Clear Visibility and Gate Safety

Health and safety on construction sites begins at the gate. Our SiteGard temporary site gates are designed to promote clear sight lines for security personnel and site managers, ensuring full visibility of who enters and exits. Unlike timber-filled hoarding gates, our systems reduce blind spots, discourage trespassers, and support better hazard awareness on site. Prioritising visibility at access points supports both operational efficiency and site safety standards.

SiteGard temporary construction gates are also designed for rapid deployment, even on uneven or no-dig ground, with options that can be repositioned as your project evolves. Whether you’re managing pedestrian traffic or large vehicle access, our solutions ensure safety without slowing down your site. All of our building site gates are built to a consistent, high standard and are fully compliant with temporary works requirements.

Construction Gate Locking Systems & Access Control

Effective security doesn’t stop at the gate—it includes how you control it. Our security gates for construction sites can be fitted with robust locking systems that deter theft and prevent unauthorised access without becoming climbing hazards. With a practical balance of security and usability, our gates support worker safety while helping you protect tools, materials, and critical infrastructure from intrusion.

Tower Crane Base Protection: CraneGard by SiteGard

Tower cranes attract unwanted attention—from thrill-seekers to trespassers. CraneGard has been engineered to secure crane bases with an anti-climb, wind-tested barrier. Unlike traditional timber hoarding, our CraneGard tower protection barriers offers safer, reusable, and fire-resistant protection that doesn’t block visibility or complicate inspections. It provides a defined safety zone around cranes and helps eliminate a major site vulnerability.

Ready-to-Install Construction Access Site Gates

We hold a wide range of SiteGard temporary gates in stock, including pedestrian site gates, double-leaf vehicle gates, and restricted access bi-fold gates, all available for same-day dispatch or collection. Built to last, even on busy London construction sites, and fully reusable, these SiteGard gates offer long-term value and can be redeployed across multiple projects.

CraneGard tower crane barriers are also held in standard sizes or can be produced quickly to meet bespoke site requirements.
