GRP Seal Plates For Manhole Covers & Chambers
Made-to-measure GRP seal plates that give manhole chambers an airtight, watertight and corrosion-free secondary seal.GRP Seal Plates for Manhole Covers in the UAE
Alphatek specialises in customised GRP (Glass Reinforced Plastic) and FRP fabrication, including GRP seal plates for manhole covers and inspection chambers. A GRP seal plate sits below the manhole cover to create a secondary airtight and watertight seal – stopping odours, gases and water ingress, and protecting the chamber below.
Our seal plates are moulded with an X-rib reinforcement for strength, fitted into galvanised or stainless steel frames and fixed with stainless steel bolts. They are fabricated to the exact clear opening of each chamber and have been supplied and installed on high-profile projects in Dubai, including infrastructure works with direct municipality involvement.

More questions about GRP seal plates
Where can I buy GRP seal plates in the UAE?
Alphatek supplies GRP seal plates made to size across the UAE. Send your chamber sizes to sales@alphatek.ae or use our request a quote form.
Do you supply the manhole cover as well?
Yes. We supply manhole covers in ductile iron, stainless steel and aluminium, so the cover and the seal plate can come from one supplier and fit the same frame.
What is the difference between a GRP seal plate and a GRP manhole cover?
A seal plate sits below the main cover and gives a secondary airtight and watertight seal. A GRP cover is the top cover itself. Read more in our guides: GRP covers and sealing plates in the UAE and GRP seal plates for tanks and chambers.
Do you make other GRP products?
Yes – see our GRP fabrication range, including linings, ladders, gully traps and tanks.
GRP sealing plate sizes, price and delivery across the UAE
A GRP seal plate and a GRP sealing plate are the same product – a glass reinforced plastic plate fixed below the manhole cover to seal the chamber. Contractors, consultants and suppliers in the UAE use both names, and Alphatek supplies both under one specification.
Sizes we fabricate
| Clear opening | Typical build | Common use |
|---|---|---|
| 600 × 600 mm | Single panel in steel frame | Inspection chambers, villas, building drainage |
| 750 × 750 mm | Single panel in steel frame | Sewer and storm chambers |
| 900 × 900 mm | Single panel or two panels | Larger chambers, pump and valve chambers |
| 1200 mm and above, rectangular | Multi-panel | Tank access, utility and infrastructure chambers |
Every plate is made to the actual clear opening of your chamber, so non-standard and rectangular sizes are not a problem.
What affects the price of a GRP seal plate
- Clear opening size and number of panels
- Frame material – galvanised steel or stainless steel
- Quantity and the number of different sizes on the project
- Whether we also supply the manhole cover above it
- Delivery location and required date
