This paper aims to two-dimensional extension of some univariatepositive approximation processes expressed by series. To be easierto use, we also modify this extension into finite sums. With respect to thesetwo new classes designed, we investigate their approximation properties inpolynomial weighted spaces. The rate of convergence is established, andspecial cases of our construction are highlighted
