Guard-coping

New standard aluminum coping supporting our lives

As architectural styles have changed throughout history, materials have correspondingly changed from wood, stone, concrete, steel, and other materials. Against this backdrop, guard-coping is a new type of aluminum coping developed by concentrating our unique technologies to meet diversified customer needs.

///Points of guard-coping///

  • 1. Standard stock of five colors to fit each design.(Inventory check is required except for silver)
  • 2. The surface treatment of R-bent coping is the same as the straight-line type. The standard delivery time is about three weeks.
  • 3. Brackets are steel-reinforced. Respective types have their distinctive characteristics, which are different in strength and quality.
  • 4. There are 18 varieties of type C and 5 varieties of type U, which can be used for a wide range of applications.
  • 5. Type U is a product that complies with common specifications by the Ministry of Land, Infrastructure, Transport and Tourism.

    Ease in handling and high quality

    Conventionally, coping has been mostly made of wood. As architectural styles have changed throughout history, materials correspondingly changed from stone, concrete, steel, and other materials. These days, coping made of aluminum, which is lightweight, durable, and repeatedly recyclable, is predominant. Guard-coping is a new type of aluminum coping developed by concentrating our unique technologies to meet diversified customer needs.

    JIS H 4100 A-6063S-T5 (For the 12 varieties of 135 – 400, aluminum alloy extruded section bars are used. The 6 varieties of 425 – 600 are finished products of section bars and plates in combination.)

    Surface treatment
    A1 and A2 (combined coating of anodic oxide and organic films) specified by JIS H 8602:2010 or equivalent specifications
    Construction
    The main bodies and corners are mounted by snapping them into the brackets outfitted to the framework. Each joint plate is mounted by fitting it to the joint part.
    Transportation
    Products are tightly packaged in cardboard boxes, etc. As a rule, they are stacked flat, and trucked with care to ensure that cargo is not damaged or crushed.

  • Guard-coping for aluminum handrails (retrofitting type)

    Aluminum handrails from embedded method to retrofitting method

    Previously, steel handrails were embedded in concrete because concrete and steel have the same linear expansion coefficient. However, the linear expansion coefficient of aluminum handrails is significantly different from that of concrete. Therefore, if aluminum handrails are embedded in concrete, cracks will occur in the concrete portion. Moreover, since aluminum is likely to cause alkali corrosion, if aluminum handrails are embedded in concrete or mortar containing a strong alkaline substance, durability of concrete and aluminum will substantially deteriorate. So the retrofitting method was developed. This is a unique method to secure aluminum handrails without embedding them.

    Features of the retrofitting method

    -All parts can be assembled on site.

    -A wide veranda space, etc., can be secured since a handrail can be installed at the end of the parapet.

    -Ideal for replacing handrails.

    Work with high durability, safety and speed is realized with no embedding of handrails
    Since the linear expansion coefficient of concrete and that of aluminum are different, if aluminum handrails are embedded in concrete, cracks will occur in the concrete portion. Moreover, since aluminum is likely to cause alkali corrosion, if aluminum handrails are embedded in concrete or mortar containing strong alkaline substance, durability of concrete and aluminum will substantially deteriorate. Therefore, in order to maintain durability of concrete and aluminum and quality of the product for a long time, as well as to enhance safety, a method that does not embed handrails is required. That is the retrofitting method.

    Features of handrails
    The angle can be adjusted by up to 6 degrees.
    The level can be adjusted by up to 15mm.
    The retrofitting method allows for shortening of the construction period and cost reduction.
