Three slot floor rail

The material of the three groove ground rail is cast iron HT200-300,with a working surface hardness of HB170-240.After two manual treatments(artificial annealing at 600-700 degrees or natural aging for 2-3 years),the accuracy of the product is stable and good.

The advantage of the three groove ground rail is that it does not need to be made into a large platform,which saves material costs and can occupy very small space,making it highly cost-effective.

The specifications of the three groove ground rail:The specific specifications can be made according to the buyer's drawings or agreed upon by both parties for production and processing.

The commonly used modeling method for three groove ground rails is sand molding.

Three channel ground rail modeling materials:molding sand,clay sand,core sand,resin sand.

Technical data for the installation of three trough ground rails:

1.The burial of the ground rail should be level with the ground decorative layer or slightly higher than 3-5mm.

After the installation of the ground rail,the horizontal deviation should not exceed 1mm within any 1m length,and the total length should not exceed 2mm.The horizontal deviation between the corresponding points of the tracks should not exceed 1mm,and the parallelism deviation between every two tracks should be less than 2mm.

3.The fixing method of the track is to use M8 iron expansion nails or shooting nails to fix it firmly at the required spacing(about 500-700mm)on both sides of the inner side of the track.The bottom surface of the track should be tightly adhered to the ground,without any virtual span gap,to prevent bending deformation of the ground rail under load.
