  • An advantage of the instant process is that the steel sheet has been previously galvanized, and rolled into a master coil. That master-coil of pre-galvanized sheet steel is then slit into thinner coil scalps. The galvanization has been applied before rolling. There are many beneficial factors to this process which does not require galvanizing facilities to be present.

Due to a solid, long-standing national standard of dimensions for highway guardrail provided by AASHTO, the vast majority of lengths of the salvaged guardrail panels being used as affordable fencing and barrier material has been produced in only limited lengths of 41 15 mm (13.5 feet) for 3810 mm (12.5 foot) span of fence or 7925 mm (26 foot) lengths for 7620 mm (25 foot) span of fence. Until now, these two lengths have been the only two options made available to consumers. However, it is expected that within the variety of applications where reuse of the highly durable reclaimed guardrail material is common, there can be developed consistent needs for panels produced at additionally specified lengths. For example: livestock containment facilities consistently prefer longer beams of guardrail shaped panel to more efficiently and economically contain their animals. The

  • Thrie-beam is approximately sinusoidal with three peaks separated equally with a height of about 83 mm.
  • the present invention addresses these deficiencies by providing a system and method by reconfiguring guardrail shaped materials and advancing that method by offering additional resources to expand the use of these reclaimed materials in a variety of alternative applications not requiring DOT approval.
  • state DOTs are able to continue to recoup nearly twice as much in selling the used materials for reuse rather than recycling.
  • farmers and other alternative users are able to afford and use these very high quality materials once reconfigured for different lengths and dimensions.
  • This calming effect has many benefits. Calmer animals can be directed in smooth, uninterrupted traffic patterns. Accidents, even fatalities, of cattle handlers are much less likely when the livestock remain calm. Furthermore, animals contained in corrals built with guardrail-shaped panels simply fair better. During the process of necessary sorting, any overexcitement of livestock tends to create circumstances where the animals are much more likely to injure themselves or other animals. Thus, the calming effect induced by guardrail panel eliminates a great deal of potential

Abstract

L'invention concerne un système et un procédé respectueux de l'environnement, pour fournir des systèmes de barrière en forme de rambarde à poutre en W et à poutre triple, qui utilisent approximativement la moitié du métal nécessaire pour une rambarde approuvée par AASHTO certifiée. Lesdits système et procédé éliminent également le procédé de galvanisation coûteux et dangereux sur le terrain en guise de matériaux anticorrosion plus simples, moins chers et plus économiques. D'autres systèmes de barrière, tels que des clôtures agricoles, sont de plus en plus demandés alors que la fourniture de rambarde approuvée par AASHTO certifiée diminue. L'invention concerne la fourniture de matériaux de travail plus légers pour ces applications de travail plus léger.
