 Bullet Proof Helmets - Often called Ballistic Helmets

Protection for your most vital organ - your brain. A bullet or high velocity fragment impact to your head will generally result in immediate fatality.

Bullet Proof Helmets are used by military, police and news personnel the World over. Surprisingly, very few life saves have ever been recorded from a gun shot. It is less surprising if you consider that fatalities from firearms in war zones are actually quite rare. Practically all fatalities in conflict zones are the result of primary and secondary fragments from an explosion. A primary fragment would be a fragment emanating directly from a blast. The secondary fragment is a consequence of the first - this might be concrete fragments from a building hit by a tank shell, shattering glass or a ceiling / building collapse.

Our bullet proof helmets will protect from blast fragments and direct strike from most standard hand gun and submachine gun ammunition. They will also protect from the obvious trauma effect of hand thrown missiles.

Selecting a Protection Level

Bullet Proof (Ballistic) Helmet. This model is a military MACH Tyle contoured to allow use on communications equipment

We recently reduced our or helmet range from six specifications to three (August 2005). The three levels will provide practically all potential buyers with their requirements without the need to be an expert in threat assessment. The options are listed in the relevant sections navigated by the above buttons.
For military buyers, the six specifications remain. We also offer “bolt-free” versions of most of our helmets. Normally we require minimum orders of 100 items to provide customer specific consignments.

STANAG (2950) Fragmentation Standard - V50 Test

STANAG is a NATO standard. The word STANAG is derived from the phrase “NATO Standardisation Agreement”.
Combat troops rarely suffer injury or fatality from bullets but are at high risk from primary (direct) and secondary (environmental) fragmentation. To combat these threats we supply a special range of Fragmentation 'F' levels whose performance is measured by a V50 value. The V50 test is the internationally recognised standard for assessing the fragmentation resistance of personal protection. The fragmentation test is conducted using a Fragment Simulating Projectile (mass=17 grains) shown extreme left in the table graphic . The test is conducted by firing the fragments at the system at increasing velocities until an average velocity of penetrating and non-penetrating projectiles is obtained. The higher the ballistic speed, measured in metres per second, the higher the rating of material. The V50 (Velocity 50% or mean velocity) is the average of the velocities recorded for six fair impacts consisting of the three lowest velocities for complete penetration and the three highest velocities for partial penetration, provided the spread is not greater than 40 metres/second.

The fragmentation Test

The test is conducted using shaped cylindrical steel fragments (silver in above picture). The 17 grain (1.1058 gms) is the most commonly used. The fragment is fired by explosive charge from a cartridge of the type shown in the above table. Alternative methods using compressed gas are also used.


Stab Vest, Stab Vests, Stab Proof Vest and Stab Proof Vests are common terms for body armour with a defined level of resistance to a knife or pointed weapon. The same also applies to bullet proof vest terminology - bullet proof vests have a defined level of ballistic resistance.
