Galvanized Greenhouse Lock Channel

Galvanized greenhouse lock channel is a rolled steel groove specially used together with wiggle wire to fix greenhouse plastic film,shade net and insect net.As a mainstream and cost-effective option among greenhouse film fixing systems,it is widely installed on hoop houses and multi-span planting greenhouses.Cooperated with elastic spring wire,it tightly holds covering materials in the groove to prevent fluttering,shifting and tearing under wind impact,which is one of the most commonly used standard fittings in global greenhouse construction.

This lock channel is made of high-quality low-carbon steel plate through continuous rolling and forming,with hot-dip galvanized surface treatment.The compact zinc layer provides basic anti-rust and anti-corrosion performance,adapting to conventional farm environments with humidity,condensation and ultraviolet radiation.Compared with aluzinc lock channel,it has a more competitive price,while aluminum lock channel costs higher.The scientifically curved inner groove precisely matches the radian of wiggle wire,forming even clamping force without sharp edges that scratch PO film,PE film and agricultural mesh materials.

The galvanized lock channel adopts modular design and can be cut into customized lengths according to greenhouse arches,purlin layout and project demands.On-site workers can fasten the channel on arch tubes,square pipes and purlins by self-tapping screws or rivets conveniently without complex pre-processing.Together with wiggle wire,it realizes quick locking and removal of films and nets.When seasonal replacement of covering materials is needed for crop rotation,the wiggle wire can be reused repeatedly,and the galvanized channel maintains stable shape after multiple cycles,effectively reducing repeated purchasing costs for growers.

The firm fixation formed by galvanized lock channel and wiggle wire keeps the greenhouse covering flat and taut.A neat film surface improves heat preservation and moisture retention inside the greenhouse,slows down material aging caused by long-term wind vibration,and extends the service life of covering films and nets.A stable covering foundation facilitates the subsequent installation of film rolling motors,internal shading equipment and irrigation pipelines.This combination effectively lowers the risk of film damage under strong wind and rain,improving the overall safety of planting facilities in inland and ordinary agricultural areas.

Various specifications including different groove widths and plate thicknesses are available to fit different wiggle wire sizes and various thickness of films and nets.It is widely applicable to vegetable hoop houses,seedling nurseries,flower sheds and conventional multi-span greenhouses.With mature technology,stable performance and favorable price,galvanized greenhouse lock channel remains the most popular choice for conventional greenhouse film fixing projects.
