Company History

Year 2001

Abundance of tubes used for oil and gas industry placed in factory warehouse

Mr. Zhao established Hangzhou Chengxin Steel Trading Co., as the Authorized Vendor of steel products and lifting slings for National Grid, which is among the China Top 100 by Fortune Magazine. Today we are still in the business of steel products as our subsidary business.

Year 2005

Rope Production

We started the manufacturing by making both Rope and Webbing. But at that time, we use Polypropylene yarn as our raw material. So, the production is mainly for Medium and Light Duty products.

Year 2014


We bought our land in Anji near Hangzhou downtown and build a 3-Floor building (with 8500 square meters) as a weaving company. Since then, we extend our business from Medium and Light Duty products to Super Heavy and Heavy Duty products for both consumer and industrial products.  

Year 2018


We expand our production from 1 Building to 3 Buildings. And now we have extra 2 building, one for steel business and another one for testing and also for warehouse. Totally, we have over 15,000 square meters. 

Year 2020


Today we are working under the brand of Solid Products Co. offering our clients with a full range of Cargo Control & Bungee Cords products for consumer markets, and a full range of cargo Lashing and Lifting products for industrial markets.
