FAQs
What are a few of the customization possibilities that one can look forward to in NKM International's manhole solutions?
NKM International offers a wide range of customization possibilities: in terms of material—selection from cast iron, composite, and stainless steel—size, shape, load capacity, surface design, coating, etc., ensuring your projects' exact requirement of manhole covers.
What material is best for a custom manhole cover?
The material choice varies depending on the specific needs of your application. Cast iron, ideal for high-traffic applications; lightweight and corrosion-resistant composite materials; and stainless steel with superior strength and resistance to corrosion. NKM International will guide you in selecting the right material suited to your needs.
What types of coatings can custom manhole covers be applied with?
NKM International offers up to several finishing choices for their manhole covers, which include black bituminous, epoxy, galvanization, and custom finishes. These coatings would help the manhole covers become more durable as well as resist corrosion. This would, therefore, allow the products to be used in different environmental settings.
Do the custom manhole solutions follow industry specific requirements, in the case of NKM International?
Yes, that is. This is because the international standards, such as EN-124, ASTM, must be abided by in the manufacturing of all the customized manhole solutions by NKM International, which ensures that quality and safety standards are met for different applications.
