Quality Balloons and Helium for Every Occasion

Is any party complete without balloons? While every party needs food, drinks, entertainment, and a main event, decorations and atmosphere set the tone for the entire event. Weddings, graduations, holiday parties, corporate events, auto dealership events, and other special occasions can all benefit from balloons, but finding the perfect ones without exceeding your budget can be difficult. That is, unless you choose to go through a specialty provider such as U.S. Alloys.

Below, you’ll find more information about several of our most popular services. If you need party balloons and/or helium for an occasion that isn’t listed on this page, please get in touch with our team and we’ll gladly help you find the right products for your event.

Party Balloons

As we briefly mentioned above, no party is complete without balloons! Momentous occasions call for momentous decorations, and we have everything you need to make sure that your guests are impressed from the moment they arrive.

We carry 17-inch balloons in standard, tropical, and jewel-toned colors. If you would like a mix of sizes or smaller balloons for the entire event, we have 12-inch balloons in standard primary colors, pastel, silk, vibrant jewel tone, satin, and other colors.

We also carry easy-to-tie discs that make tying balloons much faster and less of a hassle if you choose to fill them up yourself. And if you’d like to add another visually appealing element to your party balloons, don’t forget to ask about adding curling ribbons. We carry almost every color you can imagine!

Helium Balloon Tanks

A helium tank is a great way to ensure that you have enough balloons for the event and to keep the party going over multiple days if they need to be refilled. At U.S. Alloys, we know that it can be difficult to find the right size for any event, but we’ve specialized in industrial gas and welding supplies for more than five decades.

Whether you’re hosting a single-day event or a large sale that spans multiple days, you can trust that we’ll help you find the perfect balloon tank for your needs.
