About this deal

Detailed guidance on the installation of board protection systems is available from the Association for Specialist Fire Protection [3]. Fireproof paint products include intumescent paint for steel, water based fire retardants, kits to upgrade wooden doors and much more. Before buying any intumescent paint for steel you must make sure that a full specification has been undertaken listing all structural steel that need to be protected. About International Passive Fire Ltd Sixty minutes fire resistance can be achieved for columns when normal weight concrete is cast between the flanges and connected by shear connectors attached to the web. The concrete is retained by a web stiffener fixed at the bottom of the connection zone. The entire weathering process can take at least six months before becoming fully effective. Begin by removing surface contaminants with abrasive pads or brushes to prevent the zinc surface from being restored.

Oil is a common contaminate found on most metal surfaces. Use a cloth and a detergent or solvent like denatured alcohol to clean metal before painting or priming. Wipe the surface thoroughly. If the cleaner leaves a residue, rinse with water. Rust and corrosion are common in ferrous metals but also found in other metals. Remove rust with a wire brush, then remove dust with a damp cloth. If the metal has been painted previously, remove lose or scaling paint with a dull putty knife. You can also opt for multi-surface paint as long as steel or metal is among the listed compatible surfaces. But for what application is the steel being painted? A carbonific such as starch which combines with the mineral acid to form a large volume of carbonaceous char. An office building that is up to 30m in height (and does not have a sprinkler system) has a minimum fire resistance period of 90 minutesThe high gloss oil-based paint formula is resistant to corrosion, weathering, fading, and abrasion. You can throw anything at it; moisture, UV light, mechanical stress, it won’t budge. Meanwhile, the fire performance of concrete — with its variety of mixes and formulations — is hard to define.

Oil paints and enamel paint generally dry much slower than water-based paints. However, this drying time also varies by brand. Where periods of fire resistance greater than 60 minutes are required, only the exposed bottom flange or plate or the beam requires protection. The section factor is calculated on the basis of the heated perimeter of the bottom flange or plate. Therefore, steel beams need fire protection. If you don’t suitable protect them, your insurance will become invalid and more importantly, it can be dangerous and disastrous!

The color diversity is certainly satisfying; if you’ve been looking for rich, lively, and fun colors to spruce things up; Rust-Oleum has got it. You definitely will not want to leave your steel beams the color of the intumescent paint (white) so you will need to apply a topcoat and color over the intumescent paint once it is completely dry. I struggled to find a definite answer as to what kind of paint you should use over the top. Intumescent paint is an integral part of effective passive fire protection system. When exposed to extreme temperatures, it rapidly expands to protect the surface that it’s applied to. This prevents, minimises, or delays fire damage to building structures, ultimately providing time for occupants to evacuate safely. Our RSJ or rolled steel joists, are delivered pre-painted in Red Oxide. Red oxide primer is an anti-corrosion coating to help prevent the formation of rust, ensuring long term durability.

In this guide, Alex Chenery-Howes from CLM Fireproofing explains in greater detail how intumescent paints work, which materials they protect, and how to apply them. How do intumescent paints work? Heavyweight boards are usually in the range 700-950kg/m³ and will generally accept decorative finishes. They are typically used where an aesthetic finish is required. The first line of defense is simply cleaning the structural member with acetone, a thinner, or another type of solvent. Buro Happold used analytical and numerical models to calculate the distribution of steel temperatures that would happen during a localised fire at the base of the atrium. Guidance documents such as Approved Document B or BS9999 suggest roof structures do not require fire protection. While this might be true for the top storey of multi-storey buildings, it is not always true for complex roof structures covering larger assembly buildings such as exhibition halls, stadiums and arenas. In these buildings, the fire protection requirements of the roof structure need to be carefully assessed by a structural fire engineer.The surface profile that results depends on the type of abrasive used. “Abrasives can leave anywhere from a 0.5 profile to a 5- or 6-mm profile,” Berish said. Sprays are lightweight products that are easily and cheaply applied, but are not decorative. Their use has declined in recent years, but they are still used — particularly in large buildings that require high periods of fire resistance. Guidance
