When adding a railing  system to a porch or deck, it is important that climate is taken into consideration when choosing the material for your railings. This is particularly critical in colder climates, as extreme temperature fluctuations and moist weather conditions can wreak havoc on certain building materials. Choosing a durable railing material is particularly critical in areas that see harsh winters, as railings can provide the safety and stability needed to prevent accidental injuries, and potentially fatal falls, when there is snow and ice on the ground.
