Material & Print Options

Our Lock Sign is manufactured using industry-grade materials to ensure long-term performance in both indoor and outdoor environments. Choose from two popular material options to suit your site requirements:

Adhesive Vinyl: A flexible, self-adhesive option ideal for smooth surfaces such as walls, doors, or equipment. Perfect for temporary or low-impact use cases.
3mm Rigid PVC: A robust, weather-resistant board suitable for permanent installations in high-traffic areas such as construction zones, warehouse signage points, or loading bay signage posts.

All signs are printed using UV-stable inks to resist fading and ensure legibility over time, even in harsh working conditions.

Installation Info

The Lock Sign is designed for easy and flexible installation across various site types. Whether you're mounting the sign on a perimeter fence, a wall, or a gate, it can be affixed using screws, cable ties, or adhesive—depending on your selected material. Please note: Fixings are not included with this product, allowing you to choose the most appropriate method for your specific location and surface type.
