Bull Guards proven to promote Automotive Safety
Automobile safety is the avoidance of automobile accidents or the minimization of harmful effects of accidents, in particular as pertaining to human life and health. Special safety features have been built into cars for years, some for the safety of car's occupants only, some for the safety of others.
Distance covered by vehicles in one second (the typical human reaction time).Road traffic injuries represent about 25% of worldwide injury-related deaths (the leading cause) with an estimated 1.2 million deaths (2004) each year - World Health Organization [1]).
Major factors in accidents include driving under the influence of alcohol or other drugs; inattentive driving; driving while fatigued or unconscious; encounters with road hazards such as snow, potholes, and crossing animals; or reckless driving.

Grill Guards and Aluminum
Grill Guards and Aluminum
Grill Guards are often manufactured from Aluminum:
Aluminium is a silvery and ductile member of the poor metal group of chemical elements. It has the symbol Al and atomic number 13.
Aluminium is found primarily in bauxite ore and is remarkable for its resistance to corrosion (due to the phenomenon of passivation) and its light weight. The metal is used in many industries to manufacture a large variety of products and is very important to the world economy. Structural components made from aluminium and its alloys are vital to the aerospace industry and very important in other areas of transportation and building.
Aluminium is a soft, lightweight metal with normally a dull silvery appearance caused by a thin layer of oxidation that forms quickly when the metal is exposed to air. Aluminium oxide has a higher melting point than pure aluminium. Aluminium is nontoxic (as the metal), nonmagnetic, and nonsparking. It has a tensile strength of about 49 megapascals (MPa) in a pure state and 400 MPa as an alloy. Aluminium is about one-third as dense as steel or copper; it is malleable, ductile, and easily machined and cast. It has excellent corrosion resistance and durability because of the protective oxide layer. Aluminium mirror finish has the highest reflectance of any metal in the 200-400 nm (UV) and the 3000-10000 nm (far IR) regions, while in the 400-700 nm visible range it is slightly outdone by silver and in the 700-3000 (near IR) by silver, gold, and copper. It is the second-most malleable metal (after gold) and the sixth-most ductile. Aluminium is a good thermal and electrical conductor.

Steel and Bull Bar Manufacture
Steel and Bull Bar Manufacture
Bull Bars are often manufactured from Steel:
Steel is a metal alloy whose major component is iron, with carbon content between 0.02% and 1.7% by weight. Carbon is the most cost effective alloying material for iron, but many other alloying elements are also used.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and their distribution in the steel controls qualities such as the hardness, elasticity, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also more brittle. The maximum solubility of carbon in iron is 1.7% by weight, occurring at 1130° Celsius; higher concentrations of carbon or lower temperatures will produce cementite which will reduce the material's strength. Alloys with higher carbon content than this are known as cast iron because of their lower melting point.[1] Steel is also to be distinguished from wrought iron with little or no carbon, usually less than 0.035%. It is common today to talk about 'the iron and steel industry' as if it were a single thing; it is today, but historically they were separate products.
Currently there are several classes of steels in which carbon is replaced with other alloying materials, and carbon, if present, is undesired. A more recent definition is that steels are iron-based alloys that can be plastically formed (pounded, rolled, etc.) For more information on steel please visit http://en.wikipedia.org/wiki/Steel

Bull Bar
A bull bar (also roo bar or nudge bar in Australia) is a device fitted to the front of a vehicle to protect the vehicle (and its passengers) from damage in a collision with an animal. They vary considerably in size and form but are usually made out of welded steel or aluminium tubing and more recently polycarbonate materials.

The bull in the name refers to cattle which in rural areas can roam onto roads and highways, although other animals such as sheep and horses also pose hazards. In Australia, kangaroos are the primary hazard in many areas, hence the name roo bar.
In Australia the term roo bar refers to a generally lighter weight bull bar, more suited for sedan vehicles, although both terms are somewhat interchangeable. In northern areas where cattle are more prominent and where larger four wheel drive vehicles are used, larger bull bars may predominate and are exclusively of heavy steel fabrication.
Nudge bars are generally fitted to sedans and small SUV's, and consist of light aluminium or polycarbonate tubing which protects only the radiator grille and areas without replacing the bumper bar. Roo bars and bull bars typically replace the front bumper or fender of the vehicle and most thus require the installation of indicator light housings.
Ideally a bull bar does not hinder the entry angle of a four wheel drive vehicle, and are thus often specially designed to improve such facets of off-road performance.
Bull bars are the most effective platform for mounting electric recovery winches and spotlights. They are also often used to mount radio antennas for communications equipment such as CB radios, even though mounting above the roof provides better performance. The design of bullbars generally provides protection for the accessories mounted to them.

Traditional bull bars have limited use as a safety feature since they are built to lessen the damage to the vehicle, which contradicts modern safety thinking where controlled deformation of the vehicle is considered to be the most effective way of absorbing the kinetic energy during collision.
Some designs can also cause more severe injuries to pedestrians who are hit by cars with them fitted, particularly children. Because of this, some countries have made bull bars illegal on vehicles that weigh less than several tons.
Modern design of bull bars and roo bars, however, has advanced so that some vehicle manufacturers and aftermarket companies now offer impact bars which integrate with the vehicle safety system, such as activation of airbags after collision with the bull bar. In recent times they have become popular also as a cosmetic accessory, particularly on 4x4s and SUVs.
Plastic bull bars made from materials such as polyethylene are designed to deflect such that the vehicle might be damaged but still driveable after striking an animal. These designs are more pedestrian friendly than the same vehicle without any bull bar.[1] [2]
