Benefits of Security Gates

Security gates are designed for maximum safety and protection. They are attractive in appearance and can be automated or manually operated. We can supply them in various heights and sizes to suit the required space.

Applications

We have been installing heavy duty security gates for a wide range of purposes for over 25 years. They are recommended for use on a wide range of domestic, commercial and industrial sites for peace of mind when you need it most.

Security Gates Specification

These metal security gates can be made to British Standard requirements and come complete with posts, hinges, dropbolts and padlockable slidelatch. All gates are hot dipped galvanised to BS EN ISO 1461 and can be Polyester Powder Coated to BS EN 13438.

All our gates have optional extras that can be added to achieve best in class commercial gate systems and extra peace of mind.

Additional Security Extras

  • Mortice lock/Deadlock
  • Full Length Slam Plate-Hinge Covers
  • Padlockable Dropbolts
  • Padlock Shrouds
  • Anti-Slam Device

Unbeatable Installation Guarantee

We guarantee our commercial fencing installation for 10 years because we are confident it will last.

This week we had KNIGHT FENCING (SELSEY complete a new 5ft fence at the bottom of our garden. A very professional job was done by two workers . They arrived promptly and worked so hard to complete first class job. The new fencing looks amazing, highly recommend company . It has provided us with privacy in our garden and a safe environment for our two dogs . They left the garden very tidy .
Thank you
Deborah O.
We had a new gate installed and our double security gates made higher.

The workman were friendly, efficient and the work was carried out to a high standard.

We would highly recommend knight Fencing

Straightforward job but very efficiently done. The team arrived while we were out but contacted us by phone and were happy to carry on as requested.

Terry and Sam have done some really fabulous work for us. Totally reliable and give a full service experience for the customer. Will always go the extra mile to make sure the job is just right.

I had delivery of my gorgeous garden swing this morning. How nice to be taken by surprise that Knight Fencing really delIvered on it's promise! Recent experience has shown me that not all companies do this. Since placing my order, Jade in customer services has been fab, and I also must mention how accommodating and friendly Knight Fencing's delivery partners, F&G Transport were - they couldn't have been more helpful. These are most definitely companies you can trust!! A very satisfied customer!!

Always friendly and helpful
Competitive prices too

Thank you to Shane and the lads who recently erected my 2 metre fencing.
The lads worked hard even though the weather was against them.

Thanks again. I will definitely be using Knights fencing in the future.

A massive mention for Jade who throughout the process of my purchasing and having installed two new large rear gates has been exemplary, customer service should be taught at retail outlets by this young lady. Thank you and the gates look great.

Wonderful job these guys did - Daniel & Liam the installers were professional, polite and advised what the process was going to be.
