QIAOSHI Hesco explosion-proof bag is a kind of building material which is convenient to deploy. Outside Hesco wrapped with galvanized steel,inside is the of propylene non-woven bagQiaoshi barrier looks like a big folding bag. When using it,just spread it and filled it with the sand or soil.Qiaoshi Hesco barrier is used very widely,can build barracks, ground, walls, canteens and so on.

It’s has been 12 years from of the Iraq war in 2003.The war only bring bleed and death to people of Iraq,but also separeted the block by the Qiaoshi hesco barrier.Recently the Baghdad government has begun remove some of the blast wall.The length of these blast wall is over several hundred kilometers.These explosion-proof walls are made of welded mesh and geotextile,then filled with sand or earth.Used to protect people from the blast injuries.Most Qiaoshi hesco barrier were built by US army.With the improvement of the security situation in Baghdad,Qiaoshi hesco barrier wall is gradually being removed.Baghdad government said that except for the American Embassy, British Embassy and the Iraqi government, Qiaoshi hesco barrier wall in other areas will be removed before the end of this year.The Baghdad security has improved compared with previous.But many people living in the blast walls has a lot of challenges in life.Many people suits the life living in the Qiaoshi wall, and carries on the artistic creation in the riot on the wall.If Baghdad demolition these Qiaoshi barrier walls,it will be a fresh feeling for young people living in Baghdad.

On 30th March,Xinhua Baghdad reported that the twenty-third session of the Arabia State League summit ended on 29th,March in the capital city Baghdad. As the leaders have left, this city which has a long history of the ancient capital return to peace. After the Arab League summit started a few minutes later, the explosion occurred near the venue.Fortunately,the government prepared barriers from QIAOSHI outside the meeting.No one injured in this explosion.
QIAOSHI Hesco barrier wall is the eternal topic in Iraq after the war.Which impressed Baghdad resident most is the barriers left on the street.Each block is separated by the QIAOSHI barrier wall. No one can see the scene on the opposite of the wall.
After the Iraq war, the government set up many QIAOSHI barriers in Baghdad’s main street in order to reduce the impact by a car bombing.QIAOSHI barriers were used combined with barbed wire.The tank gun were set up behind these yellow barriers. Sometimes, people walk through the road will be shocked by these guns.

Iraq occurred two serial bomb attack in November 18th. 2 suicide bombers drive in a hotel near Baghdad attack.Few hours later, another two suicide bombers detonated explosive wrapped around the waist.They sent the mosque in the eastern town of Khanaqin two shia.Associated Press reported that the 82 people were killed in these two explosion.
The first explosion occurred at local time at eight twelve in the morning,the site of the explosion in Baghdad’s southern Asia Hotel Delhi pull jia.There are many foreign journalists to the residence, but also close to the prisoner abuse scandal has just exposed the Iraqi Interior Ministry.The foreign journalists escape from the explosion by hide uder the Qiaoshi barrier.”Thanks to the Qiaoshi Hesco barrier we will survive.”Said by James,a war correspondent of Reuters.The Associated Press said the city formed a hundred feet high mushroom cloud due to the powerful explosions in Baghdad.The cement debris flying everywhere around the restaurants.



Gabions boxes are wire containers made of hexagonal wire netting. Wire diameter varies with the hexagonal nettings. For hexagonal wire netting with no pvc coating, the wire diameter ranges from 2.0mm to 4.0mm. For those PVC coated hexagonal wire netting, the outside diameter ranges from 3.0mm to 4.0mm. The wire of the outside frame edge is one wire gauge thicker than the wire used for hexagonal wire netting.

Economic. Just fill the stone into the gabions and seal it.
Simple installation. No special technology needed.
Weather proof under natural destroy, corrosion resistant.
No collapse even under big scope of deforming.
Sludge in the stones is good for plant growing. Mixed to form a integrity with the natural environment.
Good permeation can prevent the damage by hydrostatic.
Less transport freight. It can be folded together for transport and further installation.

Gabion boxes applications:
Control and guide of water or flood
Flood bank or guiding bank
Preventing of rock breaking
Water and soil protection
Bridge protection

Protection engineering of seaside area

The designing team of QIAOSHI BARRIER held the products to the Beijing Guard Training Field of Beijing on Monday 2nd February.
The units were deployed and filled by a QIAOSHI construction team.They use the forklift truck to fill the QIAOSHI BARRIER with sand or soil.They creating a stand-alone wall over two metres tall and 15 metres wide. Guests included Chinese Army,goveronment and Embassy of many countries, observed the firing of various types of ordinance at the QIAOSHI BARRIER, including bullets, grenades, 10kg of explosives, and RPGs, testing the product to its full capabilities.
Carl,the producing manager of QIAOSHI BARRIER factory, present at the trial said:
“The barrier units were partially damaged at the front, as to be expected from such an intense stream of direct fire, but most importantly the rear of the barrier remained intact, and the structure still stood strong, still protecting. The testing was an absolute success.”

QIAOSHI BARRIER is a modern gabion used for flood control and military fortification and the name of the British company that developed it in the late 1980s. It is made of a welded gabion box and non woven geotextile.Then use temporary to semi-permanent dike or barrier against blast or small-arms. QIAOSHI BARRIER is widely used in Chinese Army.
QIAOSHI BARRIER factory has over 20 engineers designing team.We can customized different types of QIAOSHI BARRIER for our clients from Iraq,Afghan,Iran,United States,Russia and many other countries which invloved war .QIAOSHI BARRIER can also used for erosion and flood control.It became a popular security device in the 1990s.Our products continue in use for their original purpose.QIAOSHI BARRIER were used in 2005 to reinforce levees around New Orleans in the few days between Hurricanes Katrina and Rita.”These barriers are quick and easy to install when you have the right equipment, and can be stacked as high as you need. I felt safer standing next to Hescos in Iraq than concrete walls. Something the city would be smart to explore soon.”Said by Keth,a business man from America who live in Iraq.

Mesh is the number of holes in the wire mesh products.Generally, the more of the mesh holes,the smaller pore size will be. Now, for the calculation of screen area of usually use mesh holes’× mesh aperture’ formula to calculate For example: about 38mm aperature screen product,it is about 400 mesh.While the 30mm hole in the plate, which is about 500 mesh. Therefore, the mesh is actually related to the amount of hole size. Only to determine the size of the mesh in order to accurately calculate the size of the screen product. Therefore, mesh screen for calculate products overall area has a very important significance.

However, about the screen openings rate products.The application materials are different.Different country has different standard of mesh screen,in today’s industry, the most widely used standard are for the United States standards, British Standards and Japan standards.But the latter two large deviation calculation.Generally,we choose the US standard to calculate the mesh size. That is the formula given above. Mesh screen is generally referred to the number of cells per square meter has.In screen product specifications, represents the number of units of multi-use mesh holes / cm / line to be represent.

Gabions Box Type

Gabions Box Type are galvanized double twisted hexagonal woven mesh with a rectangular box shape. The compartments or cells are of equal size and dimension and are formed by internal diaphragms being placed within the basket. The compartments or cells are filled with natural stone and the diaphragms minimize stone migration within the basket providing even distribution of the stone fill throughout the basket even after structural movement. The gabion box strength comes from a double twisted hexagonal mesh of steel wire which is reinforced by selvedge of heavier gauge wire running along the edges and by transverse internal diaphragms at 1m centers.

Materials: low carbon steel wire, galvanized wire and PVC coated wire
