No. 1 Xingye Street, east side of the East Outer Ring Road, north of Chengdong Industrial Street, Leshou Town, Xian County, Cangzhou City, Hebei Province
Manhole covers are used to seal the openings of underground shafts in roads, residential communities, municipal utility networks, industrial parks, and factory sites, providing protection against rainwater, sewage, electrical, telecommunications, and gas inspection chambers. They offer load-bearing support to prevent pedestrians and vehicles from falling in, while also accommodating drainage, maintenance access, and safe passage. Available in four main categories—municipal heavy-duty, residential light-duty, composite eco‑friendly, and ductile iron—they are suitable for a wide range of applications, including roadways, sidewalks, landscaped areas, parking lots, and more.
In winter, rainy and snowy conditions, icy roads, and snow‑covered surfaces can easily cause wheels to slip and brakes to lose control. This tire chain increases friction between the tire and the road surface, effectively breaking ice and gripping snow, shortening braking distances, and preventing skidding and rear‑end甩尾. An essential safety accessory for driving on icy or snowy roads in mountainous areas, on elevated highways, and in suburban regions, it’s compatible with most passenger cars, SUVs, off‑road vehicles, pickup trucks, and other common family vehicles.

DYE-300 Electro-Hydraulic Concrete Flexural and Compressive Testing Machine
This testing machine is suitable for determining the flexural strength of concrete specimens measuring 150×150×550 mm and 100×100×400 mm, as well as the compressive strength of cement mortar and other construction materials. Equipped with electric‑hydraulic loading, load measurement via a transducer, and digital display of force values, it is an essential testing and inspection device for engineering organizations in the construction, materials, highway, and bridge sectors.
Designed by the Cement Institute of the China Building Materials Academy, this is the standard equipment specified in the national standard “Methods for Testing the Strength of Cement Mortar (ISO Method) GB/T 17671-1999,” and is suitable for mixing cement mortar specimens during specimen preparation.
