Manhole shutters give your site team a straightforward way to form a concrete surround around a manhole ring while it sits in the ground. Instead of building timber formwork from scratch, you assemble modular steel panels around the ring and pour concrete directly into the shutter. Altrad Generation's manhole shutters cover manhole rings from 675mm to 3000mm in diameter, so you can match the shutter to the ring size on your drawings without ordering a custom solution.
The system is built from three panel sections, Section A, Section B, and Section C, and you combine these in different quantities to reach the exact diameter you need. Each combination is available in two heights, 900mm and 1800mm, so you can form a shallow surround or a taller one depending on the depth of your excavation. This modular approach means one set of panels covers a wide range of ring sizes across gas, water, sewer, and drainage projects, cutting down on the amount of kit you need to keep on site or in the yard.
On deeper installations, manhole shutters work alongside a manhole box, with the shutter panels used inside the box excavation to form the concrete surround around the ring at depth. Once the ring is in place and the surround is poured, a manhole safety platform sits above it to protect your team during the rest of the construction sequence. The panels are steel and built for repeated use, so they hold up across multiple projects, and you can hire or buy them depending on how often your business needs them.
Key Features and Benefits
Covers ring sizes from 675mm to 3000mm: One set of panels adapts to almost every manhole ring diameter you are likely to encounter across gas, water, sewer, and drainage projects.
Two heights available: Choose 900mm or 1800mm shutters to match the depth of your excavation and the surround you need to form.
Three panel sections for flexible configurations: Section A, Section B, and Section C combine in different quantities, so you are not limited to a fixed diameter shutter.
Manageable section weights: Sections range from 6kg up to 55kg depending on the size and height you choose, so your team can handle panels without heavy lifting equipment in most configurations.
Works alongside manhole boxes and safety platforms: Use the shutter panels inside a manhole box excavation for installations at depth, then fit a manhole safety platform above the ring for the rest of the build.
Available to hire or buy: Choose whichever option suits the length and frequency of your project.
Frequently Asked Questions
Q. What size manhole shutters do I need?
A. Altrad Generation's manhole shutters cover manhole rings from 675mm to 3000mm in diameter. The panels are supplied in 900mm and 1800mm heights, and a combination of three panel sections, Section A, Section B, and Section C, lets your site team build the exact diameter you need from that range.
Q. What is the difference between manhole shutters and a manhole box?
A. Manhole shutters form the concrete surround around a manhole ring once it is in position. A manhole box, such as Altrad Generation's BV100/JV100 or BVB/JVB range, is the excavation support system that holds back the ground around the ring while you work. On deeper installations, you use the shutter panels inside the manhole box excavation to form the concrete surround, so the two products work together rather than replacing each other.
Q. Can I hire manhole shutters or do I have to buy them?
A. Altrad Generation offers manhole shutters for both hire and sale, so you can choose whichever option suits the length and frequency of your project.
Contact your nearest Altrad Generation branch to discuss manhole shutters for your project. Our branch teams can help you work out the right combination of Section A, Section B, and Section C panels for your manhole ring size, whether you need them for hire or purchase.
