How to choose the correct thickness for Acrylic Aquarium Tanks based on depth

Selecting the correct thickness for acrylic aquarium tanks is crucial, especially with deep tanks. Acrylic is a strong, clear material that’s often used to make fish tanks since you can keep water in it and it looks nice. But if the acrylic is too thin, it can crack or buckle under the pressure of the water. If it’s too thick, then it can be heavy and expensive without a real need. At Shanghai Lanhu, we know how crucial it is to get the right thickness so that your aquarium is always safe and looking great. The thickness is mainly a function of how deep the tank will be, because the water presses more on the walls for deeper tanks. Here’s how to pick the right acrylic thickness and why depth is such a big deal. 

Choosing the Right Acrylic Thickness for Deep Aquarium Tanks

Choosing the correct acrylic thickness for deep tanks is not a mere speculation. It’s knowing how water pressure operates, and how acrylic responds to it. The Pressure The deeper the tank, the more pressure the acrylic must withstand. Smush a thin sheet of plastic: It’s easy to bend. But if the plastic is thick, it remains robust. At Shanghai Lanhu we apply this insight to assist clients pick out their ideal size. For instance, a 12-inch deep tank may require only 1/4 inch thick acrylic while towering tanks up to 48 inches depth will need acrylic with at least ½ inch thickness or more. It thickens as water pressure increases with depth. The more the water, the harder it pushes against the tank walls. This force extrudes the acrylic outward, and so thicker stock prevents bending or cracking. 

People often think that the thicker the acrylic on all tanks to ensure maximum safety is best, but this isn't necessarily correct. Too thick leads to wasted money since the tank is charged by weight and also makes a hard-to-move (or re-sell) tank unnecessarily heavy. In addition, thicker acrylic can cut down on light coming through not good for fish or plants inside. That is why, with Shanghai Lanhu, we weigh safety against cost and looks. We find that the correct thickness also depends on tank size, shape and what fish or equipment will go inside. A large reef tank, for instance, may require thicker acrylic than a shallower small fish tank. Our crew assists you with thinking about these particulars so that the tank stays around a long time and looks nice. 

Acrylic Aquarium Thickness Chart - How To Determine The Thickness? 

Depth should be the determining factor in choosing an acrylic thickness. Pressure is gained at a rate of one atmosphere (close to 14.7 pounds per square inch) for every 33 feet below the water’s surface. That's enough to exert a lot of pressure on the bottom, so even small tanks feel like they hold bazillions of gallons. For shallow tank, acrylic can be very thin because there is low weight of the water pressing on the side. But the deeper tanks get, pressure builds up rapidly, and the acrylic has to be stronger to withstand it. In Shanghai Lanhu, we often see that depth is the first factor of acrylic water tank failure if it is too thin. 

Consider a 24-inch-deep tank for an example. The water pushes upon the walls harder than a tank of the same depth of 12 inches. Some practitioners use the same thickness for each, which can cause the deeper tank to crack or bulge. And this is the reason why thickness must increase with depth. But the size of the tank matters too. Tall tanks have more pressure at the bottom, so the acrylic must be thicker on that side. Wide tanks distribute the pressure more and may need less thickness. We will consider the thickness proposal by measuring the height, width and length of the tank acutely at Shanghai Lanhu. 

Sometimes one forgets that acrylic is also susceptible to temperature variations. Acrylic softens with hot water, and hardens again with cold. This means that if your aquarium is very deep and cold (or hot!), you might prefer a thicker acrylic for the same stress level. We always make this point to our customers, because safety is about more than just thickness it’s about how the acrylic will perform every day. Pick the thickness according to the depth and conditions thus making your aquarium secure for decades. We here at Shanghai Lanhu are proud to provide advice along with product that meet these requirements. 

How to Measure Thickness of Acrylic for Custom Wholesale Aquariums 

Acrylic Sheets Thickness for Big Acrylic Aquariums - When you decide to create a large acrylic aquarium, it is crucial to understand the thickness of your acrylic sheets. Its thickness is determined primarily by how deep the tank will be. This is because water presses with force against the walls of an aquarium, and the deeper the tank, the force becomes greater. If the acrylic is too thin, it could crack or bow, and that would be unsafe for both the fish and people in its vicinity. To determine the proper thickness, you need to first consider how high the water is going to be in that tank. Higher water will put more pressure upon it's acrylic. As a rough rule of thumb, Planell as said that for every foot in depth of water the acrylic needs to be thicker to contain the water safely. For instance, an aquarium as small as 1 foot deep may require only a mere 1/4 of an inch in thickness for the acrylic sheet. But a very tall tank, say 4 feet or more high, would probably require acrylic that was 1/2 inch thick or even thicker. Shanghai Lanhu provides this kind of calculation for many businesses and for aquarium makers. They have special formulas and tools to ensure the acrylic is just thick enough, but not so thin as to pose a danger and not too thin as to be more expensive. Don’t forget to inform the supplier about the depth if you are planning a custom wholesale aquarium project. That way, they can assist you in choosing the appropriate thickness for your tank. The correct thickness = The longest lasting tank, and the most transparent tank as thicker glass or acrylic just like aquarium size can be polished to have a perfect finish. So bear in mind the depth when measuring the acrylic thickness for your tank. 

How to Find the Wholesale Source for Acrylic Sheets for Fish Tanks 

After figuring out what thickness can meet your needs with the acrylic sheets, then comes to where to buy them. When creating several public aquarium at the same time, purchasing acrylic in bulk is a great idea, as this will save money and ensure that you get the same level of quality each time.

Some acrylic is a breeze to cut, shape and polish which makes it easier for you to build better tanks faster. Shanghai Lanhu offers easy to work with and smooth handling acrylics that will save you time and produce attractive tanks. Another key factor is the dimensions of the acrylic sheets.

What Kinds Of Common Standards For Acrylic Thickness In Wholesale Aquariums Are There?  

A general guide to acrylic tank thickness based on tank size - The Concept Acrylics team gets many questions about how a tank of specific dimensions would be determined to a certain thickness and the answer is, “it depends”. In the aquarium manufacture industry, there are general rules or standards that most shops use as well for determining what material you would use to build the tank. These standards exist, in large part, to ensure that all tanks are safe and aesthetically pleasing, regardless of who is manufacturing them. At the moment, that has been one good trend using acrylic thickness to exactly match water depth without making walls too thick or thin. This would be the thickness required to support water pressure fairly well but not waste acrylic material. For instance most of the wholesale aquariums use 1/4 inch to 1/2 inch thick acrylic for tanks up to three feet deep. The thickness should go up to 3/4 inch or even full 1 inch for deeper tanks. Sheng Zhou Pools Shanghai Lanhu, which keeps abreast of these developments and assists clients with keeping in line with today’s standards when choosing thicknesses, enabling tanks to remain aesthetically pleasing as well as safe. Another trend is toward clear, high- quality acrylics which don't yellow. This makes sure the aquarium is kept clean and bright for long time. Shanghai Lanhu employs with advanced multi-materials to satisfy the requirements. In addition, a number of wholesale aquarium manufacturers are opting for an acrylic thickness conducive to easy shaping and bonding. This is what helps make tanks with smooth edges and stronger seals, which are crucial for large aquariums. In addition to thickness, some manufacturers also factor the type of acrylic — including UV-resistant or impact-resistant varieties — into their formula for longevity outdoors or in high-traffic areas. These special form of acrylics are also offered by Shanghai Lanhu. Adhering to these new norms will help aquarium producers make tanks that customers trust and appreciate. If you’re hoping to produce attractive, durable wholesale acrylic aquariums, working with Shanghai Lanhu and keeping pace with these trends will also set you ahead of the curve.
