About Us

PolycarbonateX is a trading name of Grossi Group Ltd, registered in England and Wales (Company No. 16905972). To provide the most efficient service and technical support, we operate from two primary locations:

  • Administrative Office: 1 Delapre Drive, Banbury, Oxfordshire, OX16 3WP.

  • Distribution Center: The majority of our national orders are dispatched from our specialised logistics hub in Chesterfield, UK.

PolycarbonateX is a UK-based specialist supplier of multiwall polycarbonate roofing solutions, serving both trade professionals and DIY customers across the country. Although PolycarbonateX is a newer brand, our team brings over 15 years of hands-on experience in the roofing, glazing and building-materials industry.

We’ve spent more than a decade working directly with installers, builders, fabricators and homeowners — advising on thickness selection, rafter spacing, installation methods, and how to get the longest life out of multiwall roofing systems. That experience shapes everything we do today.

Built on real industry knowledge

Before launching PolycarbonateX, our background was rooted in:

  • Supplying roofing and glazing materials to both trade and retail

  • Helping customers measure and build pergolas, lean-tos and carports

  • Understanding the differences between brands, grades and sheet constructions

  • Troubleshooting issues like condensation, thermal movement and poor support spacing

This isn’t guesswork or generic ecommerce knowledge — it’s the practical, “everyday on-the-tools” experience that makes our advice reliable and genuinely helpful for customers.

Why we exist

We launched PolycarbonateX to solve the common issues customers face online:

Complicated buying process

Thickness choices, sheet spans, rafter spacing, end closures and glazing bars can quickly become confusing.

Lack of real expertise on most websites

Many suppliers simply list products with no guidance.

Hidden delivery details or slow communication

Customers were left unsure who to trust.

What we do differently

Our goal is simple:
Make buying polycarbonate sheets easy, transparent and accurate.

We provide tools, clear guides and real customer support so you can choose with confidence — whether you’re building your first pergola or managing roofing projects every week.

Clear, transparent service

We believe trust comes from clarity, which is why we focus on:

  • Straightforward pricing with no hidden upsells

  • UK-based customer service

  • Fast communication by phone or email

  • Specialist advice based on real installation experience

  • Reliable nationwide delivery using carriers familiar with large sheet materials

When you contact us, you speak to someone who actually understands the product — not a call-centre reading from a script.

Trade and DIY customers welcome

Our customers include:

  • Pergola and garden-room companies

  • Builders and roofers

  • Carport installers

  • Property developers and tradespeople

  • Homeowners completing DIY projects

  • Fabricators, workshop owners and small businesses

Whether you need a single replacement sheet or regular weekly orders, we support both one-off and ongoing supply.

Tools designed to help you choose correctly

To make things easier, we’ve built:

  • A Polycarbonate Calculator

  • A Multiwall Thickness Guide

  • Full Thickness-specific collections (10mm, 16mm, 25mm)

  • Installation advice and project guidance

  • Delivery estimate tools

  • Accessory recommendations based on real-world installs

These tools exist so customers feel confident — and so projects get installed correctly the first time.

Our promise

We are committed to:

  • Selling quality, branded polycarbonate

  • Offering real human help whenever you need it

  • Providing clear delivery information

  • Giving reliable guidance based on experience, not guesswork

  • Being a business that customers genuinely trust

We know that when you buy roofing materials, you’re not just buying a product — you’re trusting us with your project. That responsibility matters to us.
