Your color scheme is not doing you any favors. Red is supposed to make certain elements stand out, I feel like this whole page is yelling at me. Try to keep your color scheme to two/three colors + 1 call out color.
Suggest a few top sellers, preferably some that you carry in many sizes. As Kevin mentioned, filters would help people sort out exactly what they need.
The connect with us looks bad and is in a prime location. I'm sure this isn't your CTA for the page so I would move it towards the bottom of the page. Can use this place for the filters.
The "Plastic Storage Bins" sidebar just has the model number as a title and the price. Check your analytics to see how many people actually click on that. My guess is slim to none. Its non-descriptive and not relevant to the page. Instead, highlight 3 "top sellers" for the category they are currently viewing or something.
I would move the text below the products as they should be the main focus of the page.
The right sidebar videos are also out of place.. I highly doubt anyone would press play on one of three random videos that are 150px wide, with no titles.
There are many things you can do to improve this page.. main thing is that it is very busy and gives little direction to the visitor. Check out analytics and install something like inspectlet or clicktale to view how visitors interact with the page.
