Colors Art is a leading manufacturer and supplier of wholesale canvas stretcher bars and stretcher frames for canvas, prints, and oil paintings.

Sometimes you cannot find the right size pre-stretched canvas, so what to do? Make your own canvas to paint on of course.
Many artists sometimes feel that making their own canvas is the first step of any painting, the first step of the creative process. Some will even say that they must make their own stretcher bars as well.
Well, without going that far, which requires more tools and time than many may have, one can start with these professional manufactured stretcher bars.
We feature Best heavy and medium duty and lightweight bars, Our affordable stretcher bars have been specifically designed to create high-quality canvas gallery wraps.

Our Stretcher bars  are made from solid pine wood. Consistent quality and kiln dried lumber assures you that the bars will fit nicely together and will be straight. This is the wood of choice for most museum quality stretcher bars due to its stability,  low resin, and lignin content. The wood is kiln-dried to a moisture content below 8% which will ensure that there will be no warp or shrinkage after the canvas is applied to the stretcher frame.These are perfect for small to medium paintings.

Stretcher bars make up the greatest material cost and are the least marketable feature of any gallery wrapped print,.

Our stretcher bars feature a unique, 1.5” deep x 0.75” wide; Tongue and groove design ,tight fighting corners,designed to provide your canvas prints with robust support and a gallery quality aesthetic on the front and back side of your prints.

Each bar is rounded and beveled at the optimal angle to suspend the face of your canvas print away from the bars, eliminating visible impression lines that are commonly created by many other stretcher bars.

Our stretcher bars are pre-notched and lock together firmly and easily, eliminating the need for technical assembly and expensive framing equipment.

Top one quality in Stretcher bar producer in China

There are a lot of stretcher bar factories in China , but the one who can give consistent quality are very few . Stretcher bar or assmbled frame seems very easy product , but it is not easy to control the quality consistency , because all the wooden products have to face the same problem that is bend problem , the main reason for the bend problem is the dry degree or said moisture degree , how to control the moisture degree and the methord of dry the wood is the key to decide the wood will bend or not in the future . Wood type also has infulence of the bend degree. The wood that grows up in the cold weather will be better than the one grown in hot weather , for example Russia Pine will be better than the Newzeland Pine , because the pine grows in Russia growing speed is slower , the density will be much higher , that is the market is mainly choose the pine stretcher bar for gallery wrapped canvas . Many customer does not need so high quality , we also have paulownia for your selection in economical range , paulownia features much lighter weight , but the color is not so nice , and many factories can not produce them very solid , but if you buy from us will never meet this problem , we are the first one in China producing pine stretcher bars , and never loose any customer because of quality issue . I remember there is one old customer told me once that there is one supplier in China offer a price 20% cheaper than you , I told him , we do trust what you said , in China any price can achieved, if you say 30% cheaper also exsist , but what we can guarantee is that the stretcher bar or frame we sell to you every piece can be used, how many defects they can give you maybe 30%, maybe 50% or more , than means the finally the cost you buy from them is higher than us , because their defect rate is very high , such as wood bended , frame tonge and groove can not joint well , the thickness of each bar is not equal (the frame will be winkle when the thickness of each bar is not equal) ,the length of each bar is not equal or tolerance is big (this will cause the frame not to be evenly square), the wood is not solid enough because it has not been dried properly 

Loose Stretcher Bar Packing  :

Loose stretcher bars are regular packed in carton box , no matter it is  with tongue and groove or 45 degree cutted , carton boxes is a best choice for the customer , it can well protected the two end of the stretcher bar in the process of packing , and if that is possible we donot suggest customer buy ready made canvas frame , because it occupies a lot space , the shipping cost is very high since Covid-19, it is not easy to make money , so if one container of loose strether bars will valued more than the assembled frame .

Ready made assembled canvas frame packing：

For the assembled stretcher frame we regular used nest packing on the pallet , the pallet is bend wrapped and then the EPE film and outsid is  plastic film , this packing is very safty  and very easy to loading . Our canvas frame quality is very good with the solid pne wood , finger joint pine , the tolerance control is very strict , it can match the automatic canvas stretching matchine Fast Frame 1000 plus, Fast Frame 1200 plus, which is made Imaging Solutions AG . We are confident to say we are the tope one in china who can control the quality consistency with the experince of over 16 years .

3m length stretcher bar moulding Packing：

3m photo frame or called picture frame moulding raw wood is also popular in the market , we regular packed them with the bend and then the EPE film outside is the plastic film wrapped , we will stick the label on the two end of the bundle , which can help customer quick find the items that they need very quickly . In fact 3m photo frame bar has much higher quality request , because 3m length is much easy to bend compared with the shorter size , luckily our quality standard can control the bend degree very well .
