gci

Of the roofing options available in most developing countries, galvanized corrugated iron (gci) sheeting is by far the most widely used

Chapter 3 1991

In the mid - 1970s, FCR developments focussed on the production of sheets of about one metre square, since the aim was to substitute gci and ac sheets.

Chapter 3 1991

Asbestos cement (ac) sheets are also extremely popular in many countries for similar reasons as gci, and also on account of their better thermal performance and fire resistance.

· Cadmium, chromium, nickel, tin, zinc and a few other metals are mainly used as constituents of alloys to suit a variety of requirements, or as coatings on less resistant metals to improve their durability, a common example being galvanization (zinc coating) of corrugated iron sheets (gci).

· The main advantage of the technology is that a cheaper, and thermally, acoustically and aesthetically more satisfactory substitute for galvanized corrugated iron (gci) sheeting can be manufactured locally on any desired scale (usually small or medium scale), with a relatively small capital investment and large job creating effect.

Chapter 4 1988

· The standard hut has gci sheets for cladding and roof covering, and plywood boards for interior lining and suspended ceiling.

· The thermal and acoustical performance of FC/MC roofing is superior to that of gci sheets.

Chapter 4 1988

· Corrugated setting moulds: gci or ac sheets, enough for two days production.

Chapter 10 1988

The corrugated FC sheets are laid on timber roof structures in much the same way as gci and ac sheets.
