Galvanizing knowledge of galvanized steel springboard
The process of urbanization is constantly accelerating. In order to cater to the new era, the scale of urban old area renovation and new area expansion is constantly increasing, and the construction industry is also receiving increasing attention. The rise of the construction industry has also promoted the development of building materials and equipment, with galvanized steel springboards being an important component. One important aspect of galvanized steel springboard is: galvanizing. How much knowledge do you know about galvanizing? Defa Foundry takes you to understand the difference between hot dip galvanizing and cold dip galvanizing.

How to install ductile iron manhole covers
Cast iron products are used in many occasions in daily life. It should be noted that cast iron products not only have strong plasticity, but also have much higher toughness than normal carbon steel. It is precisely because of the high-quality performance of cast iron castings that manufacturers choose to process cast iron products into ductile iron manhole covers.

The History of Ductile Iron Well Covers
The underground of a major city is filled with underground utilities: sewers, rainwater channels, steam tunnels, and utility corridors. Usually, channels called manholes are regularly excavated into these underground pipelines for maintenance personnel to access them. A manhole cover is necessary so that people can clean, inspect, or repair underground utilities. In the third water supply tunnel in New York City, the manhole cover can be as shallow or as deep as 70 floors. The manhole cover is a circular iron plate that sinks into the streets and sidewalks, preventing pedestrians from falling into the manhole.

Steel springboard is a good helper for fire prevention
In recent years, with the continuous development of high-rise buildings, the types of scaffolding for building exterior walls have also been constantly innovated, but the springboard has remained basically unchanged. Due to low prices and deep-rooted traditional habits, the update of springboards is very slow. Currently, a considerable number of construction sites in the market still use bamboo (wood) springboards.

Precautions for the use of steel pipe scaffold fasteners
To improve the product quality and safety of fasteners during use, not only must the quality of fasteners be strictly controlled, but also the use of fasteners should be strictly managed. The correct usage method not only ensures maximum construction safety, but also helps to extend the lifespan of fasteners.
