PPG STEELGUARD: Wembley Stadium, London


PPG STEELGUARD offers long-term fire and anticorrosive protection with superb aesthetics

The Customer

Opened in 2007, Wembley Stadium was built on the site of the previous 1923 incarnation. The 90,000-capacity venue (105,000 combined seating and standing) is the second largest stadium in Europe, behind only the Camp Nou in Barcelona, and serves as England’s national stadium. It is the sole home venue of the England national football team, and hosts the latter stages of top-level domestic club cup competitions.

Designed by Foster and Partners and HOK Sport (now Populous), it includes a partially retractable roof. A signature feature of the stadium is the 134 meter high (440 ft) Wembley Arch. With a span of 317 meters (1,040 ft), this steel arch is the longest single-span roof structure in the world and, uniquely for a stadium, requires beacons for low-flying aircraft.

The Challenge

The reconstruction of the Wembley National Stadium took 5 years from 2002 to 2007. On such a prestigious and iconic structure, the challenge was to provide an extremely durable anticorrosive and fire protective coating system that would meet all British fire protection standards, while producing an attractive finish to complement the structure’s visual appeal.

The low-thickness system also had to be able to coat every shape and size of steel component used on the intricate steel arch.

The Solution

To answer the complex brief, PPG Protective & Marine Coatings (PPG) proposed and supplied the complete anticorrosive and fire protective coating system for all externally and internally exposed steelwork of the stadium.

The Customer

Wembley National Stadium Limited

The Location

London, United Kingdom

The Challenge

To provide a long-lasting fire and anticorrosive protective coating system able to coat every shape and size of steel that meets British fire protection standards with an excellent aesthetic finish.

The Solution

Application of PPG STEELGUARD FM560 solvent-based intumescent coating for fire protection. PPG SIGMACOVER 435, PPG SIGMACOVER 456 HS and PPG SIGMACOVER 520 coatings for corrosion protection to the internal and external steelwork.

The Benefits

The PPG STEELGUARD FM560 coating provides optimal fire protection with a 60-minute fire rating. The complete system delivers outstanding anticorrosive protection and an attractive surface finish for the complicated steel structures.

The Result

Excellent visual appearance with a hard-wearing anticorrosive and fire protective coating system.

A combination of PPG SIGMAFAST 302, PPG SIGMACOVER 435, PPG SIGMACOVER 456 HS and PPG SIGMADUR 520 coatings were applied to the steel structures in order to provide a high level of anticorrosive protection.

For the required fire protection, a full three-coat fire system was used to meet the various environmental conditions around the stadium. The PPG STEELGUARD 3146 primer and PPG STEELGUARD FM560 solvent-based intumescent coating were chosen because they provide the required 60-minute fire rating. The topcoats used were PPG STEELGUARD 2458 & PPG AMERCOAT® 450SG to guarantee optimal aesthetics. The three-coat system was applied at a dedicated offsite contractor’s premises and delivered to site ready to erect.

The Result
