Our stretchers do not require glue or nails to  for assembly,they easily slot together creating the perfect canvas frame.

Instead they incorporate mortise, tenon joints and wedge keys, allowing the stretcher bar to be adjustable . Sold in boxes or singles with wooden wedges, supplied with every pair are tapped into corner slots to allow re-tensioning of canvas. Reglular the Gallery wrapped stretcher bar is 38mm deepth, 38mm width , since Covid-19, the shipping cost is very high , this add the cost of the stretcher bars imported from long distance , so we recommend a economic stretcher bar which is 38mm deepth , but 28m width , the deepth did not change , but the width a little narrow , this does not efffect the frame thickness ,but cost can be about 25% cheaper  , For frame szie below 40cm*50cm  donot need brace bar or cross bar , regular size over 50*60cm will need a single brace , now the market for stretched canvas or canvas prints is very fierce , cost control is very competitive , we recommend 28mm*38mm thickness pine stretcheer bars with knot , if you want to stretched for artist canvas , we have some cotton linen blend canvas for your choice , they match together will be an economic stretched canvas for art supply .

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 .
