The present invention discloses that an anti-sliding batten with preventing thermal expansion being applied on that setting up a shield on a roof with the batten and comprising a plurality of projecting blocks spread on at least one surface of the batten with a suitable interval for any two adjacent projecting blocks. By means of the present invention, the friction between the anti-sliding batten and the shield is increased, hence two of them are tightly touched each other for promoting working safety; further, careless workers being sliding to fall down is then prevented and the phenomena of shrink and expansion are no longer exist.
