We pride ourselves on fully understanding each flood schemes specific requirements and providing years of experience in the flood defence sector.

MME make their flood gate components and structures in the UK. MME offer shorter lead in times than any of our flood defence gate competitors. Typically our lead times are 6-8 weeks from drawing approvals. In comparison to 12 week lead times from our competitors.

At MM Engineering we offer the following flood defence gate types:

Single Swing Flood Gate–This gate type is generally for openings up to 6mtrs wide and depending on structural design calculations up to 3mtrs high. MME flood gates are operable by one person therefore can be closed within 30 seconds using our bespoke spindle mechanism.

Double Swing Mitred Design Flood Gates –
Double flood gate designs are offered when the swept path for single flood gates are obstructed. Clients can purchase our gates up to 14mtrs wide and over 3.5m high. This is subject to the civil design capabilities of each flood defence project. Operators can close our double flood gate in under 2 minutes. Double flood gate designs have 2 spindle starter latches and a central locking latch to lock both gate leafs together.

Bi-Fold Swing Flood Gates –
We offer the bi-fold gate when obstructions in the gates swept path are present and a single gate is still preferred. MME offer a bespoke bi-fold flood gate that has a reduced foot print. This gate follows all the same design criteria as the double and single flood gates.

Fully Automated Flood Gate Systems
At MM Engineering we also offer a fully automated double flood gate system, the system includes the following components;

commercial flood gates
  • Hydraulic operating cylinder for each gate leaf: the cylinder size is governed by certain design specifics these include but are not limited to the flood gate size and weight, wind loading and any impact loads the flood gate may need to withstand.
  • Hydraulic power unit and electric motor for each cylinder.
  • Siemens LOGO plc and control panel.
  • Open and close sensors.
  • Full safety system: which ensures the flood gate complies with BS EN 12453:2001- Industrial, commercial and garage doors and gates.

Sliding Flood Gates–When there is no space to operate a swing type flood gate MM Engineering also offer a sliding flood gate option. These can be manual at widths of 6mtrs and no greater in height than 1mtr. Any sizes above this would lend itself to automated operation. The sliding flood gates can be hidden away between flood defence walls. These gate types suit projects where aesthetics are an important factor especially relevant to heritage and conservation areas.

All of the above flood gate designs can be offered in Mild-Steel and Stainless Steel to suit the specific project design requirements. The swing type flood gates can pivot a full 180 degrees.

MME Flood gates include a comprehensive set of third party design calculations. There are times when project specific design calculations are required and these are completed by Chartered Engineers. Fabrication work is undertaken by fully coded welders. These flood gates are designed to adhere to the following design codes including relevant national annexes;

 Flood Gate Design Codes
MM Engineering flood gate designs are suitable for casting the bespoke frame into new flood defence walls in addition to face fitting via resin anchor and studs. Our design engineers can adjust our cast in gate pillar designs to accommodate your exact on-site flood wall layout.

The sealing sill of our floodgates is a Stainless Steel 200 x 10 anti-slip plate. This allows vehicular and pedestrian access with no trip hazard present. The floodgates seals are EPDM foam with a protective neoprene sleeve therefore prolonging the seals design life.

MME Mild-steel flood gates paint system is a marine epoxy coating with a 25 year life. This system is specified for use on offshore oil rigs while also being used for commercial ship hulls. Mild-steel flood gates can have a design life of 40-50 years depending on maintenance procedures.

316 stainless flood gates are available with a garnet blast finish and can achieve a design life of 70years in addition to a maintenance programme.

Full design specifications for our flood gates and product literature are available on request. MM Engineering are confident we have the flood defence product that will meet your project specific needs.
