Designing industrial websites is quite different from designing a small business website or online store with e-commerce. When it comes to designing websites for industries, a designer needs a different approach. What helps an online store to attract sales for example cannot be helpful for a manufacturing company, as their target audiences are different. Where online stores deal with retailers or consumers, industrial manufacturers deal with wholesalers, suppliers, and distributors.
Industrial websites have special requirements. Other websites are not as complex, have less documentation, content, and so on. There are many differences. Experienced industrial website designers understand this well.
