Protecting metal grades have developed over time, with armoured plate now half the thickness wanted 30 years in the past but retaining the identical stage of security. That is particularly necessary for armoured autos when utilizing armour metal to guard them in opposition to penetration or blast forces. Protecting efficiency must be achieved with out making the car excessively heavy.

SSAB, a world chief in quenched and tempered metal, makes use of superior metallurgical processes to provide Armox® and Ramor® ballistic steels designed to offer most safety. Assured thickness, flatness and bending properties all contribute to creating workshop-friendly supplies, and Armox safety grades additionally supply excessive toughness relative to hardness, permitting good bending properties. Moreover, Armox and Ramor metal plates are “cleaner” than most different steels, with a low carbon content material that makes welding simpler.

Customized constructed armoured autos

Ballistic Armor Applied sciences (BAT) on the outskirts of Johannesburg, South Africa, completely makes use of SSAB steels for his or her tasks. BAT was fashioned 30 years in the past, however has grown considerably during the last ten years, supplying armoured autos for money transporters SPV, Constancy and G4S. Different clients embrace the French police pressure, however most clients are based mostly in Africa.

Boasting 100 staff and a producing facility of 700,000m2, BAT at present produces about 20-25 autos a month, with a complete of round 2000 cash-in-transit autos for buyer fleets within the nation. Beginning with an authentic design, BAT works with its clients to seek out out what their actual necessities are, that are then transformed right into a mechanical design based mostly round SSAB metal. BAT additionally offers full safety software program and {hardware} improvement in-house. Fabrication, chopping, welding, and portray are all accomplished in-house, then the components are moved into BAT’s meeting corridor for set up on the autos, with the chassis equipped by the shoppers.

Partnership with SSAB

“We’ve bought a really lengthy relationship with SSAB,” Kuno Kerlen, managing director, Ballistic Armor Applied sciences, says. “For 25 years now, we’ve been completely utilizing their metal. Our merchandise are often called the perfect within the nation, and that’s an excellent hyperlink with SSAB, which is often known as the perfect on this planet, so I feel that’s an exceptionally good partnership.”

Kerlen says SSAB can provide all of BAT’s wants because of the intensive vary of steels they’ve. For ballistic safety it’s the hardness of the metal that issues: “It’s fairly difficult. Each single bullet works in a different way. The best way that it might punch by means of or splatter metal. So, it’s a really specialised kind of metal. We use numerous grades from them, from completely different hardness to completely different thickness. We even use a few of their ‘regular’ merchandise in a number of the structural purposes that we’ve…throughout the vary. Mainly, all their armoured steels.”

“I feel the specialised nature of SSAB additionally ties in with our specialised enterprise. Their armoured division, their speciality metal division, is kind of specialised and so are we.” Kerlen says that this relationship means he can converse to SSAB consultants in Sweden each time he must, however SSAB even have an area department, with stockholding and gross sales reps, which he says is extraordinarily handy and useful.

Prime quality ballistic metal

As BAT works completely with SSAB steels on daily basis, they have to be assured that its high quality is constant, and that the metal can be simple to work with.

“You’ll want to weld it. You’ll want to bend it. You’ll want to minimize it,” factors out Kerlen. “And the SSAB stuff is sweet. You understand it’s constant, the standard is excessive. Tolerance is all the time on the optimistic aspect – they don’t take probabilities with it. You understand if it’s presupposed to be 4 millimetres and [sometimes] its 4.1 or 4.2. You’ll all the time see that it’s 10% over the precise required thickness. They’ll take a look at the ballistics on the lowest stage, and they’re going to all the time guarantee that their manufacturing tolerances are all the time on the optimistic aspect. It provides a little bit of confidence for ourselves and our shoppers to know that the product goes to do what it’s presupposed to.”

Working with the metal can be a optimistic expertise says Kerlen: “While you bend it – it all the time performs brilliantly. We’re very pleased with this metal.”

Challenges of coping with ex-military grade weapons

Sadly, in South Africa, as in different places all over the world, ex-military weapons are utilized by criminals to assault autos, with doorways being opened by blasting. “At the moment in South Africa, and I feel additionally in Europe to a lesser diploma, we’ve bought numerous issues these days with blasting,” explains Kerlen. “[The criminals] truly blast the autos open as an alternative of taking pictures them.”

Kerlen says that whereas the ballistics a part of the armour safety is working nicely, you will need to be aware that South African weapons are completely different than those that the majority worldwide requirements are set for: “We have now barely completely different weapons right here, and a few of them punch loads more durable than say American weapons or European weapons. So, we’ve needed to do our personal testing right here and guarantee that the steels are appropriate. There are internationally recognised requirements, however we’ve bought our personal requirements right here that that we carry on ballistic ranges, because of the fairly potent weapons which are accessible – outdated army weapons.

“We guarantee that we will specify the steels that are required for the South African weapons versus European or worldwide norms. We’re assured in what the metal can do. Nevertheless, now with the blasting, that brings it to a very completely different stage. You should guarantee that the autos are in a position to withstand blast. How does it carry out below blast? In order that’s actually the problem we’ve had for the final 4 or 5 years.”

BAT has been working in partnership with each the native police and SSAB to look at completely different steels to withstand blasting. “We’ve accomplished numerous blast testing right here domestically with the police and attempting completely different steels out. And I feel we discovered some good formulation, and that’s additionally been with the enter from SSAB and the blast specialists that they’ve. Particularly, in Finland and Sweden, so it’s been collaborative,” says Kerlen. “We present them the outcomes and say, ‘that’s nice. Have a look at that. Have a look at this. Possibly that might be higher. Possibly that thickness? Possibly that’s as much as design.’ And we’ve been very profitable in South Africa, to try to mitigate the blast menace.”

Future traits for armour safety

Kerlen says that sadly, he sees blasting as a pattern: “These are profession criminals that might be attacking these autos so they might transfer to stealing cigarettes or cell telephones. I feel that’s the one pattern that we’re going to be seeing. Blasting is clearly a brand new pattern, and it’s not going to cease in South Africa. And there are additionally issues that might go exterior of our enterprise mannequin, like embassies or corporates that may be a bit extra cautious in future, attributable to world terrorist threats, [which are] going to want excessive ranges of safety.”

For BAT, trying ahead Kerlen is contented together with his present technique of regular progress. “I carried out a technique about 4 or 5 years in the past, which we’re nonetheless busy with at this stage. We’ve grown fairly dramatically, and we’ve provide you with some options from a technical viewpoint for blasting. I feel that’s our subsequent large problem – to good that and to develop that into completely different merchandise.

“We’re nonetheless nicely into our technique, which includes rising the markets vertically in addition to horizontally, and so it’ll be a much bigger deal with Africa. The market is comparatively small in comparison with South Africa, however small drops make a river. [Some African countries] at the moment are beginning to get laws – obligatory specs for armoured autos. And I feel we’ve bought a novel answer for Europe, however I don’t assume I’m going to be doing Europe anytime quickly. I imply we’ve bought fairly an enormous market right here.”
