Sigma Bespoke Multi-Purpose Safety Pallet Gate

This new concept pallet gate has features designed to solve specific problems not addressed by other models.

What’s so special?

Conforms to BS EN ISO 14122-3:2016 Mezzanine Gates

It does not protrude over the floor edge. No overhead bars when loading. Less risk of damage during the loading operation.

Fitted with 100 mm high Aluminium kick plate

When the operator pulls down the inner gate, the mechanisms incorporated in the side frames automatically pivots up the two edge gates to the vertical position either side of the opening. See the video on this page.

When used with standard pallets the side frames can be reduced for space-saving and allows good access to a pallet on three sides. This model can also be used with a vacuum handling crane for unloading bags or sacks etc. Read more about special applications below. With the inner gate raised this model offers more usable floor space for confined areas.

The design can be adapted for use with inward opening doors or roller shutters and is especially useful for use with hoists on low runway beams. When the gates are fitted to deeper side frames it allows the inner gate to fold up, under the runway, behind the load when landed. 

The construction is a combination of our tried and tested standard tube and component construction merged with specially designed pivot joints and tube rotators.

This design allows us to produce a bespoke low-cost gate which can be easily adapted (See below) not only in height, width and depth but will also be easy to assemble and adjust on-site to ensure optimum operation


  • All galvanised
  • Safety yellow thermoplastic (Warm to touch) coated tube and galvanised components
  • Special RAL colour powder coated tube 

Special applications

In addition to normal forklift loading, this model can be used with hoists, in doorways, and with vacuum handling cranes - See notes belowThe Sigma model is offered to bespoke requirements -

*Dimensions are approximate only. Due to differences in the tube clamps and the assembly process, the actual
dimensions may vary. Any critical dimensions such as hole fixing centres should be determined when the product
is actually on your site. We reserve the right to change the design without notice

 Bespoke inside width - We recommend that you allow at least 200 mm load clearance for the inside gate 

 Overall width including side frames. e.g. 2000 mm gate inside width = 2800 mm gap required (Overall width)

 Standard Installation requires 8 x M12 Bolts/Anchors (Not provided)

Special notes:  (You can tell us about any special features or extras you require in the additional information box.

The depth of the gate will vary according to the height and depth of the load to be cleared by the fold down the inner gate and the length of side frames. Overall height varies according to the length of side frames.

Usually, there is a trade-off between space-saving and load clearance requirements. The longer we can make the side frames the lower the fold down inner gate can be to clear the load. 

For minimum height with a fold-down gate behind load depth, we recommend that you allow at least 150mm load clearance on inside height to use pallet truck to remove load..

Information we need:

The maximum size pallet(s) or load W x D X H. We will need to know the unrestricted headroom above the gate location.  The available gap for the gate to operate within. The available operating depth and how the gate will be loaded e.g. forklift or overhead hoist. 

.Loading by hoist

Sigma with hoisr

If you intend to use the gate for loading with a hoist with or without doors, the side frame will need to be of sufficient length for the inner gate to fold back up behind the load.

The inner gate needs to be closed (Vertical) to access the load. The load has to be landed to disconnect from the hoist within the landing safety area. By landing onto a suitable trolley or pallet allows a non-wheeled load to be moved further in.

We will need the height to the underside of the runway beam.  

Special note: If headroom is very tight you may need to alter the hoist 
feed system as the gates could foul the hanging festoon cables or change feed to a conductor bar system.

Please download Sigma Hoist Loading Questionnaire PDF

Unloading load/pallet with a hoist

Sigma with sack lifter

For applications where the palletized load is to be unloaded e.g. vacuum hoist for sacks. The side frames can be made with minimum depth and the inner gate raked forward in the folded position when shut. This allows the hoist to swing over the entire pallet.

If you can give us the precise dimensions we can calculate the optimum dimensions required to clear the load.

Note: We also supply the Vaculex sack lifter shown in the photo.

Doorway applications

Sigma gate in roller shutter

This model can also be used with inward opening doors (See case study or roller shutter opening. If the door has a deep ledge or external dock, it may be possible to install the gate totally outboard of the door. The inner gate can be folded down when the door is opened

Alternatively, to instal the gate as shown left, you will need to drill 6 x 50 mm diameter holes in the wall, three each side of the door frame for the active mechanism tubes which hold the outer gates. The wall can be grouted flush around the holes after installation. 

We will require the proposed hole cross centres and the thickness of the wall to finalise the arrangement.

The outer or edge gates have a kick plate which will need to land on a ledge. If no ledge exists, you will have to bolt a door width bracket to the wall under the outer face door sill. This is an ISO standard requirement to prevent items from falling through the gap between the door sill and the kick plate.

Below you'll find some handy answers to Frequently-Asked Questions relating to this product.

Question: Are floor fixing bolts supplied with a pallet gate?


Floor fixing bolts are not included with the gate as floor material and thickness vary greatly. The base feet have 14 mm dia holes. You will need M12 bolt sets for wood or steel floors. For concrete floors, anchor bolts should be used. Thin wooden floors may need extra large washers underneath to relieve stress around the hole. Check the number of bolts required in the pdf layout which can be downloaded on the product page.

If the underside of a wooden floor is blocked off, you may have to use coach bolts or rubber nuts for better grip. The rubber nut for an M12 bolt will require an M24 hole. The nut is a synthetic rubber sleeve with a flange head and a threaded brass insert at the opposite end. Used in hollow base materials where the anchor can expand in the cavity.

Question: How long does it take to install a pallet gate?


Generally, it takes about two hours for two semi-skilled operatives to install a pallet gate on a mezzanine floor. If an existing handrail has to be removed it may take longer.

A risk assessment should be carried out prior to installation to include fall protection. Drilling into the floor (Concrete) or through the floor, which will require safe access to the underside of the floor to fit nuts and washers to fixing bolts. No welding is required.

If you have to make a gap it should be no more than 160 mm (80 mm per side) wider than the overall width of the chosen gate. You can download a pdf layout showing the dimensions on the product page.

Before you commence installation please read the installation instructions supplied with your pallet gate. If you can't find the instructions please contact us for another copy. Ensure the area of installation is clear and that all the gate sections are accounted for as shown in the installation instructions.

Question: Can you supply additional handrails for my project?


Yes, we supply ready-made posts and handrails for mezzanines and platforms in conformance with BS EN ISO 14122-3:2016. See our handrails here.

Question: Why buy Mezzbarriers pallet gates?


The Mezzbarriers range differs from other pallet gate systems and methods of construction, various advanced features are incorporated into the design, production and finish with the clear aim of optimising the high quality and long life of the product.

Vibration resistant Interclamp® fittings with stainless steel screws for increased corrosion resistance have been subjected to stringent vibration endurance resistance tests by an accredited independent test laboratory. In high quality galvanised finish – Interclamp components and tube are hot-dipped galvanised to BS EN ISO 1461:2009 giving a corrosion resistant finish for extended life.

Special high-strength fabricated bolted components where needed to protect excessive leverage weak points are zinc sprayed finish. Pivot points have no-maintenance nylon bushes.

Kick plates are in aluminium material. 6063T6.- Alloy tube is used in some wider models to reduce operator fatigue.

All parts are replaceable in the event of damage.

Question: Do your pallet gate have a Health and Safety Executive (HSE) approval?


Our double gate systems comply with BS EN ISO 14122-3:2016 in design and test criteria for mezzanine gates.

The HSE and other experts say that these approved types of safety gate must always be used to secure the loading area as they safely protect all employees from moving loads and falling injuries during the loading process. And, at all other times too!

Question: Can you install my pallet gate?


Unfortunately no, but don’t worry, we include installation and safe use instructions.

Our pallet gates are very simple to install with just a few tools. Our pallet gates as shipped with all the main sections pre-assembled and installation usually takes about two hours for two semi-skilled operatives.

As platform surface materials vary, we don’t include fixings. You will need to drill holes for M12 bolt sets or anchors depending on the floor construction.

Question: Do you provide a pallet gate site survey?


No, but we have successfully supplied pallet gates all around the UK and as far as North America and Australia without us visiting the site. Just a few dimensions are needed. To get started download our Pallet gates at-a-glance (PDF).
