Plastic Handrail Capping Installation

Our fitting team is highly skilled and trained in all aspects of fitting plastic handrail covering and also carry also relevant health and safety certificates for todays Main Contractors stringent health and safety procedures they have to satisfy

Mounting of the handrail capping

The handrail capping should be heated sufficiently to a temperature of approx 170 degrees in order to make it pliable and suitable for mounting. For short installations even hot water or a large enough hair dryer will suffice but the Bio Thermic Hot Air Blower will render the best and most efficient method of fitting. The handrail is slowly guided through the hose and heated which makes it soft and pliable and then opening the lateral trims of the section the capping is hooked onto the mild steel core rail and pressed on by hand. A wiggling motion is soon a skill you pick up the more you fit. Whilst cooling the handrail capping will adopt its original shape and by slight contraction will adhere itself to the banister.

For narrow bends, ( minimum inside distance should be twice the width of the flat bar ) the handrail may need heated slightly more than usual until maximum elasticity is achieved. During the installation the covering must be pulled and stretched on the outside to prevent wrinkles on the inside. To assure proper fitting the use of canvas masking tape is recommended on the outside of the bend to hold the capping in place until it has cooled down. This process does requires a level of experience and newcomers should have trial attempts in the workshop prior to fitting on site.


If handrails are heated above 250 degrees they become soft like wax. For continuous runs, mitred joints and the fitting of end caps then the capping will need welding by means of a heated blade. After carefully cutting the ends to be welded the ends are placed either side of the heated blade until the plastic reaches melting point ( smokes ) . The blade is then carefully slide from between the surfaces and the adjoining faces of the plastic are pushed together under pressure for a few seconds to bond together. A thick seam will have formed and this is then carefully removed using a sharp Stanley knife when cooled and then filed down using a smooth file.


Once installation is complete and you have tidied up any corners, mitres and cap ends the surface of the capping will need cleaning with a solvent called Tetrahydrofuran. This is a solvent and all safety precautions and protective equipment should be worn at all times when using it. A lint free cloth is soaked in the solution and in a one step fast motion wipe the surface of the handrail.

Warning: A second or lingering motion of the application can result in creating a blurred finish instead of a shine.
