- STEEL TAPE - also known as surveyor's or engineer's tape is made of a ribbon steel-designed for most conventional measurements in surveying and engineering works
- METALLIC TAPE - sometimes called woven tape. They are made of water-proof linen fabric into which are woven longitudinally small brass, copper, or bronze wires to increase its strength and reduce stretching.
- NON-METALLIC TAPE -woven from selected synthetic materials with strong dimensional stability-coated with a plastic material to reduce the effects of moisture, humidity and abrasion-safe to use when working around electrical installations
- INVAR TAPE -a special tape made of alloy nickel 35% and steel 65% - very low coefficient of thermal expansion - it is less affected by temperature changes-it requires careful handling since the alloy is soft and somewhat unstable
- LOVAR TAPE -newer type of measuring tape which has properties and cost somewhere between those conventional steel and invar tape
- FIBERGLASS TAPE -made by weaving fiberglass in longitudinal and transverse pattern -strong and flexible and will not shrink or stretch appreciably with changes in temperature and humidity - best suited in the vicinity of electrical equipment
- WIRE -before the flat steel tapes were produced, they were utilized in measuring lengths - used in hydrographic surveys
- BUILDER'S TAPE - tapes having smaller cross sections and are lighter in weight than the engineers tape -tapes are graduated to suit commonly used dimensions in building constructions
- PHOSPHOR-BRONZE TAPE - rust proof tape designed for use in the vicinity of salt water
- NYLON-COATED STEEL TAPE -flexible crack-resistant steel core tape with coating of permanently bonded non-conducting nylon -designed to be resistant to corrosion and immune to rust
