Unlike many blast deflectors you'll find out there, Rocketry Works' steel blast deflectors are sturdy stock. Made in America of solid steel, we designed these plates to be strong enough to sustain not just the heat of many low power flights, but also the higher temperatures of mid power launches, and even the sustained burn of a rocket stuck on the launch rod. If you try that on your traditional 24 gauge blast deflector, and you'll wind up with a perforated piece of steel.

Rocketry Works deflectors are designed to be compatible with the Rocketry Works launch rod mount, and also with the Estes launch pads when used with the Rocketry Works Blast Deflector Stand-off. Their 5 inch diameter makes these plates suitable for rocket diameters of 4 inches or less, so the motor exhaust squarely hits the blast deflector, and not the launch pad or the ground. Be sure to size your launch rod to fit the size of your rocket.

This blast deflector is made of 1/32 inch thick 20 gauge steel, and is suitable for low power flights on D motors or smaller

Rocketry Works uses steel for its blast deflectors and launch rods, not stainless or galvanized materials like other manufacturers often use. This is because for items that see the brute end of model rocket motors, we believe that solid steel is more suitable for the purpose, and that there is little benefit in using more expensive materials. While steel will develop a rusty patina over time, stainless or galvanized steel will get messy when you fly rockets on it over and over again, just the same. These are parts of your launch gear that you will be maintaining regularly, and it's a good idea to store blast deflectors in a bag or other container so the rocket motor residue doesn't make a mess. We seek to improve durability and keep your costs lower where it makes sense to do so.
